Message identifier	Error message	Explanation
PA0001	manual restart settings requires file activation string "restart"	Values for parameters dt_restart or/and restart_time have been given in the &runtime_parameters-NAMELIST. This also requires to give the file activation string "restart" with palmbuild-option -a, because otherwise the restart files wouldn't be generated at the end of the PALM run. Repeat the run with -a ".... restart" or remove parameters dt_restart or/and restart_time from your NAMELIST-file.
PA0002	illegal coupling mode: ...	This message is related to the atmosphere-ocean coupling or pure vertical nesting implemented in PALM. Internally, the variable coupling_mode defines the coupling setup used for the current respective model run. It may have one of the values "atmosphere_to_ocean" (atmospheric part of a coupled run), "ocean_to_atmosphere" (ocean part of a coupled run), "precursor_atmos" (a precursor atmosphere run), "precursor_ocean" (a precursor ocean run), "vnested_crse", (the coarse simulation of a vertical nesting run) "vnested_fine" (the fine simulation of a vertical nesting run) or "uncoupled" (atmosphere or ocean run without any intended coupling). This error message means that the initialization of the coupling did fail because coupling_mode has a value different from the ones mentioned before. Possible reasons might be trying a coupling between two atmosphere runs (or two ocean runs), or problems with the palmrun script.
PA0003	dt_coupling is not set but required for coupling mode "..."	This error appears if the temporal interval for the data exchange dt_coupling is not explicitly set in case of runs with coupled models (e.g. atmosphere - ocean).
PA0004	coupling mode "...": dt_coupling = ... is not equal to dt_coupling_remote = ...	For coupled runs the temporal interval for the data exchange dt_coupling must be explicitly set and must have the same value in both models (dt_coupling has to be set in PARIN and PARIN_O). See also coupled runs.
PA0005	coupling mode "...": dt_coupling <= 0.0 is not allowed and is reset to MAX(dt_max(A,O)) = ...	This error occurs if an invalid value for dt_coupling is used in the parameter file. dt_coupling must be > 0.0 and equal in both models (dt_coupling has to be set in PARIN and PARIN_O). The letter A in the error message on the left refers to Atmosphere and the letter O to ocean. See also coupled runs.
PA0006	coupling mode "...": restart_time = ... is not equal to restart_time_remote = ...	restart_time has not been set properly (equal) in the atmosphere and ocean parameter file. See also coupled runs.
PA0007	coupling mode "...": dt_restart = ... is not equal to dt_restart_remote = ...	dt_restart has not been set properly (equal) in the atmosphere and ocean parameter file. See also coupled runs.
PA0008	coupling mode "...": time_to_be_simulated_from_reference_point = ... is not equal to time_to_be_simulated_from_reference_point_remote = ...	The simulated time from the reference point is stored internally in the variable time_to_be_simulated_from_reference_point. In coupled mode both times must be equal. This error might occur when precursor runs are used with different startup times and the coupling is initiated inappropiately. See coupled runs for a detailed description of the setup for precursor runs.
PA0009	dx in atmosphere is not larger or equal than dx in ocean	Coupled runs allow to use different grid resolutions in atmosphere and ocean. It is, however, not allowed to use a finer grid resolution in the atmosphere than in the ocean.
PA0010	Domain size in x-direction is not equal in ocean and atmosphere	Coupled runs are only possible, if the horizontal model domain size is equal in both, atmosphere and ocean. Check the settings for dx, dy, nx and ny to avoid this error.
PA0011	dy in atmosphere is not larger or equal than dy in ocean	Coupled runs allow to use different grid resolutions in atmosphere and ocean. It is, however, not allowed to use a finer grid resolution in the atmosphere than in the ocean.
PA0012	Domain size in y-direction is not equal in ocean and atmosphere	Coupled runs are only possible, if the horizontal model domain size is equal in both, atmosphere and ocean. Have a look at the settings for dx, dy, nx and ny to avoid this error.
PA0013	illegal value given for loop_optimization: "..."	See parameter loop_optimization for allowed values, and check your parameter file.
PA0014	a non-flat topography does not allow ...	There are several features which do not work together with a non-flat topography. See parameter topography for possible restrictions and appropriately modify your parameter file. For a complete list of not allowed parameter settings due to a non-flat topography see check_parameters.f90.
PA0015	Using synthetic turbulence generator requires initializing_actions = "set_constant_profiles" or "read_restart_data"	When switching on the synthetic turbulence generator by setting use_synthetic_turbulence_generator = .TRUE., PALM has to be initialized using either constant profiles (initializing_actions = "set_constant_profiles") or loading data from a previous run (initializing_actions = "read_restart_data"). Other initialization actions do not support the synthetic turbulence generator.
PA0016	unknown solver for perturbation pressure: psolver = "..."	See parameter psolver for allowed values, and correct your parameter file.
PA0017	output of more than 300 profiles requested	The total sum of output profiles given via parameters data_output_pr and data_output_pr_user is greater than 300. You may either reduce the number of output profiles, or ask the PALM group (via the trouble-ticket system) to extend the bounds of PALM internal arrays to allow for more than 300 profiles.
PA0018	illegal value for data_output_masks or data_output_masks_user: ...	Possible reasons are: (a) a typo in the parameter file related to masked data output, (b) a user-defined variable has not been defined in user_check_data_output.f90, (c) the string length of the user-defined variable exceeds the current limits (see here). For possible output quantities see data_output_masks.
PA0019	unknown surface type: surface_type = "..."	See parameter surface_type for allowed values, and appropriately correct your parameter file.
PA0020	unknown multigrid cycle: cycle_mg = "..."	See parameter cycle_mg for allowed values, and appropriately correct your parameter file.

PA0022	unknown advection scheme: momentum_advec = "..."	See parameter momentum_advec for allowed values, and appropriately correct your parameter file.
PA0023	momentum_advec or scalar_advec = "..." is not allowed with timestep_scheme = "..."	The 5th order advection scheme is conditional unstable in conjunction with euler or runge-kutta-2 integration. Instead, use timestep_scheme = runge-kutta-3.
PA0024	unknown advection scheme: scalar_advec = "..."	See parameter scalar_advec for allowed values, and appropriately correct your parameter file.
PA0025	use_upstream_for_tke is set to .TRUE. because use_sgs_for_particles = .TRUE. and scalar_advec /= 'ws-scheme'	This is just a warning telling you that the simple upstream discretization is used for the advection term of the TKE equation instead of the one that you have set with parameter scalar_advec. This is required in case of using SGS velocity components for particle transport, because non-diffusiv advection schemes may cause large artificial vertical gradients near the surface, which create numerical instabilities in the particle transport. You can avoid output of this warning by explicitly setting parameter use_upstream_for_tke in the parameter file (initialization_parameters-NAMELIST).
PA0026	advection_scheme scalar_advec = "bc-scheme" not implemented for loop_optimization = "cache"	For the Bott-Chlond scheme loop_optimization = "vector" must to be set.
PA0027	unknown timestep scheme: timestep_scheme = "..."	See parameter timestep_scheme for allowed values, and appropriately correct your parameter file.
PA0028	negative weighting factor	A negative weighting factor might occur if the timestep is too long. Try to adjust dt.
PA0029	momentum advection scheme "..." does not work with timestep_scheme "..."	For timestep_scheme = 'runge-kutta-3' only momentum_advec = 'ws-scheme' or 'pw-scheme' gives a numerically stable solution.
PA0030	initializing_actions = "..." unkown or not allowed	See parameter initializing_actions for allowed values in initial runs (of a job chain). For a restart run, please set initializing_actions = 'read_restart_data' .
PA0031	initializing_actions = "set_constant_profiles" and "set_1d-model_profiles" are not allowed simultaneously	Set either initializing_actions = 'set_constant_profiles' in your parameter file, if the 3d-model shall be initialized with constant profiles, or set initializing_actions = 'set_1d-model_profiles' if the 3d-model shall be initialized with profiles of the (stationary) solution of the 1d-model.
PA0032	initializing_actions = "set_constant_profiles" and "by_user" are not allowed simultaneously	Set either initializing_actions = 'set_constant_profiles' in your parameter file, if the 3d-model shall be initialized with constant profiles, or set initializing_actions = 'by_user' , if the 3d-model shall be initialized with profiles to be provided by the user in routine user_init_3d_model of the user-interface.
PA0033	initializing_actions = "by_user" and "set_1d-model_profiles" are not allowed simultaneously	Set either initializing_actions = 'by_user' in your parameter file, if the 3d-model shall be initialized with profiles to be provided by the user in routine user_init_3d_model of the user-interface, or set initializing_actions = 'set_1d-model_profiles' , if the 3d-model shall be initialized with profiles of the (stationary) solution of the 1d-model.
PA0034	bulk_cloud_model = .T. is not allowed with humidity = .F.	It is necessary to turn on humidity for the use of cloud physics.
PA0035	Using synthetic turbulence generator requires bc_lr = "dirichlet/radiation"	The synthetic turbulence generator requires a non-cyclic boundary condition along x direction with an inflow at the left domain boundary.
PA0036	humidity = .TRUE. and sloping_surface = .TRUE. are not allowed simultaneously	If alpha_surface is set to a non-zero value in order to use an inclined surface, the parameter sloping_surface is internally set .TRUE.. I.e., in the case of alpha_surface /= 0.0 the simultaneous use of humidity = .TRUE. is not allowed.
PA0037	Using synthetic turbulence generator requires bc_ns = "cyclic"	The synthetic turbulence generator only supports non-cyclic boundary conditions at the left/right boundary. In north/south direction, cyclic boundary conditions must be set.
PA0038	turbulent_outflow = .T. requires bc_lr = "dirichlet/radiation"	When using the turbulent outflow method, non-cyclic boundary condition along the x direction must be used. See also turbulent_outflow.
PA0039	Using synthetic turbulence generator in combination with turbulent_inflow = .T. is not allowed	A turbulent inflow can only be generated by either the synthetic turbulence generator or the turbulence recycling method. Using both at the same time is impossible.
PA0040	LWC is not conserved during collision! LWC after condensation: ... LWC after collision: ...	LWC means liquid water content. This should not happen. Please write a ​ticket.
PA0041	plant_canopy = .TRUE. requires a non-zero drag coefficient, given value is canopy_drag_coeff = 0.0	When simulating a plant canopy, a non-zero canopy_drag_coeff must be set in the parameter file under NAMELIST &plant_canopy_parameters. The canopy model in PALM adds an additional sink/source terms to the momentum equations, the prognostic equation for temperature, and the subgrid scale turbulent kinetic energy equation. In case of humidity = .TRUE. or passive_scalar = .TRUE., an additional source/sink term is added to the prognostic equation of the respective scalar. If canopy_drag_coeff = 0.0, the additional terms equal zero and there would be no effect on the flow.
PA0042	use_top_fluxes must be .TRUE. in ocean mode	In ocean mode, fluxes at the water surface must be prescribed as driving boundary conditions. In atmosphere-ocean coupled runs, these fluxes are provided by the atmosphere run.

PA0044	dt = ... <= 0.0	The parameter dt (time step for the 3d-model) must not be set to a value <= 0.0.
PA0045	cfl_factor = ... out of range 0.0 < cfl_factor <= 1.0 is required	The Courant-Friedrichs-Levy factor used in the timestep condition must be within the given limits. See also cfl_factor .
PA0046	baroclinity (ug) not allowed simultaneously with galilei transformation	The Galilei coordinate transformation (see galilei_transformation) is not allowed under baroclinic conditions (where the geostrophic wind varies with height). Modify either ug_surface or galilei_transformation, or set use_ug_for_galilei_tr = .FALSE. appropriately in the parameter file.
PA0047	baroclinity (vg) not allowed simultaneously with galilei transformation	The Galilei coordinate transformation (see galilei_transformation) is not allowed under baroclinic conditions (where the geostrophic wind varies with height). Modify either vg_surface, or galilei_transformation appropriately, or set use_ug_for_galilei_tr = .FALSE. in the parameter file.
PA0048	variable translation speed used for Galilei-transformation, which may cause instabilities in stably stratified regions	You have set both galilei_transformation = .TRUE. and use_ug_for_galilei_tr = .FALSE., which means that the translation velocity to be used in the Galilei transformation will be newly calculated after every timestep. From past experiences, this may cause numerical flow instabilities within stably stratified, non-turbulent regions.
PA0049	unknown boundary condition: bc_lr = "..."	See parameter bc_lr for allowed values, and appropriately correct your parameter file.
PA0050	unknown boundary condition: bc_ns = "..."	See parameter bs_ns for allowed values, and appropriately correct your parameter file.
PA0051	non-cyclic lateral boundaries do not allow psolver = "..."	Using non-cyclic lateral boundary conditions requires the multigrid method for solving the Poisson equation for the perturbation pressure. You can choose this method by setting the parameter psolver = 'multigrid' or 'multigrid_noopt' .
PA0052	non-cyclic lateral boundaries do not allow momentum_advec = "..."	Using non-cyclic lateral boundary conditions requires to use either the Wicker-Skamarock or the Piacsek-Williams advection scheme for momentum. You can choose one of these methods by setting the parameter momentum_advec.
PA0053	non-cyclic lateral boundaries do not allow scalar_advec = "..."	Using non-cyclic lateral boundary conditions requires to use either the Wicker-Skamarock or Piacsek-Williams advection scheme for scalar quantities. You can choose one of these methods by setting the parameter scalar_advec.
PA0054	non-cyclic lateral boundaries do not allow galilei_transformation = .T.	The Galilei coordinate transformation can only be used with cyclic horizontal boundary conditions. Either use bc_lr = bc_ns = 'cyclic' , or set galilei_transformation = .FALSE. in the parameter file.
PA0055	turbulent_inflow = .T. requires initializing_actions = 'cyclic_fill' or initializing_actions = 'read_restart_data'	Using a turbulent inflow requires that the 3d arrays have to be initialized by cyclically repeated data from a prerun or by restart data. Set parameter initializing_actions appropriately and follow the instructions at turbulent inflow.
PA0056	illegal value for reference_state: "..."	See parameter reference_state for allowed values, and appropriately correct your parameter file.
PA0057	boundary condition bc_e_b changed to "..."	You have set both bc_e_b = (u*)**+neumann, and constant_flux_layer = .FALSE., which is in conflict, since this type of boundary condition requires a constant flux layer. bc_e_b has been set to 'neumann' instead.
PA0058	unknown boundary condition: bc_e_b = "..."	See parameter bc_e_b for allowed values, and appropriately correct your parameter file.
PA0059	unknown boundary condition: bc_p_b = "..."	See parameter bc_p_b for allowed values, and appropriately correct your parameter file.
PA0060	Output at every timestep is wanted ("dt_..." = 0.0). The output interval is set to the fixed timestep dt = "..."s.	Occurs only when netcdf_data_format > 4 and dt /= -1 as an informative message. When using parallel NetCDF the output time interval must be >0. Using dt_do = 0.0 (output at every time step) is equal to setting the output interval to dt.
PA0061	unknown boundary condition: bc_p_t = "..."	See parameter bc_p_t for allowed values, and appropriately correct your parameter file.
PA0062	unknown boundary condition: bc_pt_b = "..."	See parameter bc_pt_b for allowed values, and appropriately correct your parameter file.
PA0063	unknown boundary condition: bc_pt_t = "..."	See parameter bc_pt_t for allowed values, and appropriately correct your parameter file.
PA0064	both, top_momentumflux_u AND top_momentumflux_v must be set	If you want to give a momentum flux as top boundary condition, you have to give both components top_momentumflux_u and top_momentumflux_v at the same time.
PA0065	boundary_condition: bc_pt_b = "..." is not allowed with constant_heatflux = .TRUE.	You have tried to set both, a Dirichlet surface boundary condition for temperature (with bc_pt_b = 'dirichlet' ), and a surface sensible heatflux (with surface_heatflux /= 0.0). Please decide, if you like to give either the surface temperature or the surface heatflux as boundary condition, and omit one of the two parameters in the parameter file.
PA0066	constant_heatflux = .TRUE. is not allowed with pt_surface_initial_change (/=0) = ...	If you give the sensible heatflux as surface boundary condition (using parameter surface_heatflux), you must not specify anything about the surface temperature at the same time (e.g. with parameter pt_surface_initial_change).
PA0067	boundary_condition: bc_pt_t = "..." is not allowed with constant_top_heatflux = .TRUE.	You have tried to set both, a Dirichlet boundary condition for temperature at the top (with bc_pt_t = 'dirichlet' ), and a sensible heatflux at the top (with top_heatflux /= 0.0). Please decide, if you like to give either the temperature or the heatflux as boundary condition at the top, and omit one of the two parameters in the parameter file.
PA0068	unknown boundary condition: bc_sa_t = "..."	See parameter bc_sa_t for allowed values, and appropriately correct your parameter file.
PA0069	boundary condition: bc_sa_t = "..." requires to set top_salinityflux	You have chosen a Neumann boundary condition for salinity at the top (by setting bc_sa_t = 'neumann' ), but you did not provide a salinity flux at the top. Please provide parameter top_salinityflux in the parameter file.
PA0070	boundary condition: bc_sa_t = "..." is not allowed with top_salinityflux /= 0.0'	You have tried to set both, a Dirichlet boundary condition for salinity at the top (with bc_sa_t = 'dirichlet' ), and a salinity flux at the top (with top_salinityflux /= 0.0). Please decide, if you like to give either the salinity or the salinity flux as top boundary condition, and omit one of the two parameters in the parameter file.
PA0071	unknown boundary condition: bc_..._b ="..."	See the respective parameter description in the documentation, and appropriately correct your parameter file.
PA0072	unknown boundary condition: bc_..._t ="..."	See the respective parameter description in the documentation, and appropriately correct your parameter file.
PA0073	boundary condition: bc_..._b = "..." is not allowed with prescribed surface flux	You have tried to set both, a Dirichlet surface boundary condition for humidity / passive scalar (with bc_q_b / bc_s_b = 'dirichlet' ), and a surface latent heatflux / scalar flux (with surface_waterflux / surface_scalarflux /= 0.0). Please decide, if you like to give either the surface humidity / scalar or the surface latent heatflux / scalar flux as boundary condition, and omit one of the two parameters in the parameter file.
PA0074	a prescribed surface flux is not allowed with ..._surface_initial_change (/=0) = ...	If you give the latent heatflux / scalar flux as surface boundary condition (using parameter surface_waterflux / surface_scalarflux), you must not specify anything about the surface humidity / scalar at the same time (e.g. with parameter q_surface_initial_change / s_surface_initial_change).
PA0075	boundary condition: bc_uv_b = "..." is not allowed with constant_flux_layer = .TRUE.	You have tried to set both, a Neumann surface boundary condition for horizontal velocity (with bc_uv_b = 'neumann' ), and a constant flux layer between the surface and the first vertical grid point (with constant_flux_layer = .TRUE.), which are contradicting conditions. Either set constant_flux_layer = .FALSE. or bc_uv_b = 'dirichlet' in the parameter file.
PA0076	unknown boundary condition: bc_uv_b = "..."	See parameter bc_uv_b for allowed values, and appropriately correct your parameter file.
PA0077	unknown boundary condition: bc_uv_t = "..."	See parameter bc_uv_t for allowed values, and appropriately correct your parameter file.
PA0078	rayleigh_damping_factor = ... out of range [0.0,1.0]	Adjust the value of rayleigh_damping_factor in your parameter file to the allowed range.
PA0079	rayleigh_damping_height = ... out of range [0.0, ...]	Adjust the value of rayleigh_damping_height in your parameter file to the allowed range. This error may appear if you have reduced the domain height in your current run (e.g. by reducing the number of vertical grid points) without adjusting the height at which Rayleigh damping shall start.
PA0080	preprocessor switch for fftw is missing	You have set fft_method = 'fftw' , but the fftw-code has not been activated by the corresponding cpp-preprocessor switch. Add '-D__fftw' to the %cpp_options line in the configuration file, touch file fft_xy.f90 (e.g. by executing command "touch trunk/SOURCE/fft_xy.f90" and re-compile (i.e. call palmbuild.
PA0081	"..." = 0.0 while using a variable timestep and parallel netCDF4 is not allowed.	When using parallel NetCDF output (netcdf_data_format>4) the number of output time levels must be calculated in the beginning of the simulation (see e.g. #PA0384). With a variable time step it is not possible to determine how many output time levels are needed to do an output at every time step. Therefore you have to set a fixed time step dt.
PA0082	number of statistic_regions = ... is not allowed	Adjust parameter statistic_regions in your parameter file to a value >= 0.
PA0083	normalizing_region = ... must be >= 0 and <= ... (value of statistic_regions)	The region number given by normalizing_region must be within the range [0, statistic_regions ]. Adjust normalizing_region appropriately in your parameter file.

PA0092	data_output_pr = ... is not implemented for humidity = .FALSE.	The listed entries in the parameter file under data_output_pr are only available for humidity= .T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).
PA0093	data_output_pr = ... is not implemented for passive_scalar = .FALSE.	The listed entries in the parameter file under data_output_pr are only available for passive_scalar= .T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).

PA0095	data_output_pr = ... is not implemented for bulk_cloud_model = .FALSE. and humidity = .FALSE.	The listed entries in the parameter file under data_output_pr are only available for bulk_cloud_model= .T. or bulk_cloud_model= .F. and humidity=.T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).
PA0096	data_output_pr = ... is not implemented for bulk_cloud_model = .FALSE. and cloud_droplets = .FALSE.	The listed entries in the parameter file under data_output_pr are only available for cloud_droplets= .T. or bulk_cloud_model=.T.. There could also be a typo in data_output_pr (an output variable was used that does not exist in PALM).
PA0097	illegal value for data_output_pr or data_output_pr_user = "..."	No matching variable was found for the given identifier in the parameter file. Possible reasons are: (a) a typo in the parameter file, (b) a user-defined variable has not been defined in user_check_data_output.f90, (c) the string length of the user-defined variable exceeds the current limits (see here).
PA0098	illegal value for data_output_pr = "..."	No matching variable was found for the given identifier in the parameter file. This error is most likely related to a typo in the parameter file (a output variable was used that does not exist in PALM).
PA0099	netCDF: netCDF4 parallel output requested but no cpp-directive __netcdf4_parallel given, switch back to netCDF4 non-parallel output	netcdf_data_format > 4 has been set. This requires netCDF4 features including parallel file support, which have to be activated by setting the cpp-switches -D__netcdf4 and -D__netcdf4_parallel in the configuration file (%cpp_options). It also requires a netCDF4 library which supports parallel I/O. Set -I, -L and -l options in compile (%compiler_options) and load (%linker_options) options of the configuration file appropriately. Job will be continued with netcdf_data_format = netcdf_data_format - 2.
PA0100	momentum_advec of the restart run differs from momentum_advec of the initial run	The advection scheme for the momentum equations momentum_advec used in the restart run differs from the advection scheme used in the corresponding initial run. The advection scheme that is used in a restart run must be the same as the one that was used in the initial run.
PA0101	scalar_advec of the restart run differs from scalar_advec of the initial run	The advection scheme for scalar quantities scalar_advec used in the restart run differs from the advection scheme used in the corresponding initial run. The advection scheme that is used in a restart run must be the same as the one that was used in the initial run.
PA0102	number of output quantities given by data_output and data_output_user exceeds the limit of 500	The total number of output quantities listed in data_output and data_output_user exceeds the maximum of 500. To increase this limit, the standard PALM code has to be modified. In case you have little experience with the PALM code use a trouble ticket for a query to increase the maximum output number.
PA0103	output of "e" requires constant_diffusion = .FALSE.	Output of the subgrid TKE e listed in the parameter file under data_output or data_output_masks is only available for constant diffusion= .F..

PA0107	output of "..." requires cloud_droplets = .TRUE.	The quantities ql_c, ql_v, ql_vp are only calculated in case of cloud_droplets = .T..
PA0108	output of "..." requires bulk_cloud_model = .TRUE.	For the output of some quantities related to clouds and humidity bulk_cloud_model= .T. must be set. For example, the water vapor mixing ratio qv requires bulk_cloud_model= .T.. Also, humidity = .T. must be set. If you want to simulate the humidity without condensation/evaporation processes, use only humidity = .T. and choose output quantity q for output of the water vapor mixing ratio.

PA0112	output of "..." requires cloud_scheme = kessler or seifert_beheng	The quantities pra* and prr* are only calculated if cloud_scheme = kessler or cloud_scheme = seifert_beheng.
PA0113	temporal averaging of precipitation amount "pra*" is not possible	The quantity precipitation_amount pra* listed in data_output contains already the summed precipitation of the last precipitation_amount_interval. Therefore, remove the substring _av of pra*.
PA0114	illegal value for data_output or data_output_user = "..."	No matching variable was found for the given identifier in the parameter file. Possible reasons are: (a) a typo in the parameter file, (b) a user-defined variable has not been defined in user_check_data_output.f90, (c) the string length of the user-defined variable exceeds the current limits (see here).
PA0115	illegal value for data_output = "..."	No matching variable was found for the given identifier in the parameter file. This error is most likely related to a typo in the parameter file (a output variable was used that does not exist in PALM). For possible output quantities see data_output.

PA0140	invalid soil layer configuration found (dz_soil_center(k) <= 0.0)	By setting zs (the center of the soil layers), the depths of the individual layers is calculated by PALM itself. This errors points towards a misconfiguration because a soil level is set within an already established soil layer. Check dz_soil.
PA0141	coupling requires PALM to be compiled with cpp-option "-D_parallel"	Coupling is only allowed in parallel and not in serial mode. You have to compile PALM with the preprocessor option "-D_parallel". Add this option to the %cpp_options line in your configuration file .palm.config....
PA0142	absolute temperature < 0.0 at zu(...) = ...	Within the PALM code (in bcm_init), the hydrostatic pressure profile is calculated for a neutrally stratified temperature profile t(z) = t_surface-g/c_p*z(k). If the height of the model domain is too large, the absolute temperature will become negative, which is not allowed. This error usually appears when both grid stretching is switched on and too many grid points along z are used. Try to reduce the number of grid points (nz), switch on the grid stretching at larger heights (see dz_stretch_level) or reduce the grid stretching factor (dz_stretch_factor).
PA0143	k=... j=... i=... ql_c=... part(...)%wf=... delta_r=...	This error occurs due to a spurious interaction of the production and depletion of supersaturations if the applied time step is too large. Please re-run the simulation with a shorter time step.
PA0144	#1 k=... j=... i=... e_s=... e_a=... t_int=... delta_r=... particle_radius=...	This error occurs if the droplet radius becomes negative. This might be related to a too long time step or an (artificial?) accumulation of super-droplets in one grid cell.
PA0145	illegal value for outflow_source_plane:...	The position of the source plane for the turbulent outflow method is not given or outside the model domain. Assign a value inside the model domain: dx <= outflow_source_plane <= nx*dx

PA0157	nonzero bulk velocity requires conserve_volume_flow = .T. and conserve_volume_flow_mode = "bulk_velocity"	The bulk velocity is used to prescribe a volume flow which then should be conserved. This, however, requires conserve_volume_flow = .T. and conserve_volume_flow_mode = "bulk_velocity".
PA0158	no vertical boundary condition for variable "..."	Routine advec_s_bc which calculates the advection term for scalar quantities using the Bott-Chlond scheme was called for a variable, which does not have a specific boundary condition implemented (Adding top and bottom boundaries according to the relevant boundary conditions is not possible). This should not happen. Please submit a trouble ticket.
PA0159	no term for component "..."	Routine buoyancy was called for a different wind component than the u/w-component while an inclined surface was used. In case of an inclined surface (see alpha_surface) the buoyancy term appears in the equation of motion of the w-component and u-component. There is no buoyancy term implemented for the v-component as the surface can only be inclined in x-direction and no buoyancy term is required for the v-component. This should not happen. Please submit a trouble ticket.
PA0160	non-cyclic lateral boundaries along x do not allow calculation of spectra along x	In case of non-cyclic conditions spectra would be largely affected by the non-cyclic lateral boundaries since this conflicts with the basic assumption used for the FFT that the spatial extention in the x and y-direction are infinitely large. See also data_output_sp.
PA0161	sorry, calculation of spectra in non parallel mode is still not realized	Calculation of spectra in non-parallel mode is not implemented.
PA0162	non-cyclic lateral boundaries along y do not allow calculation of spectra along y	In case of non-cyclic conditions spectra would be largely affected by the non-cyclic lateral boundaries since this conflicts with the basic assumption used for the FFT that the spatial extention in the x and y-direction are infinitely large. See also data_output_sp.
PA0163	run will be terminated because it is running out of job cpu limit remaining time: ... s termination time needed: ... s	In case that restart_time has not been set manually, PALM determines internally when a new restart run has to be carried out depending on the setting of termination_time_needed. Within the remaining time PALM will, for example, copy binary files for restart runs, archive or transfer result data. Have a look at Initialization and restart runs for further information.
PA0164	run will be terminated due to user settings of restart_time / dt_restart, new restart time is: ... s	A restart run is established by PALM due to the setting of restart_time and/or dt_restart and the new restart time is calculated.

Only certain files are allowed to be re-opened to prevent errors. If you are sure that the file can be re-opened without causing any errors, you may add the file-id to the list in routine check_open. See also the list of I/O-files.
PA0167	opening file-id ... not allowed for PE ...	Certain files are only allowed to be opened on a certain PE (in most cases only on PE0). Please check if your file can be opened on this PE and choose a different file-id.
PA0168	opening file-id ... is not allowed since it is used otherwise	Certain file-ids are reserved for files used temporarily outside of the main program. Please refer to the list of I/O-files and choose an unused file-id.
PA0169	current user-interface revision "..." does not match the required revision r....	You are using a user-interface which does not match the installed PALM revision. One reason might be that the default user-interface of the newest PALM revision has been changed by the PALM developers (e.g. because some parameters have been added to parameter-lists of subroutine calls). Please carefully read the source code change log, where these kind of changes are announced, and where also hints will be given for how to adjust existing user-interfaces.
PA0170	pointer for array ".." can't be associated	This is an internal error message from the pmc (PALM model coupler) which is responsible for data exchange in nested runs. Please submit a trouble ticket if you are sure that you did not modify the source code of the model coupler (pmc_interface_mod.f90).
PA0171	netCDF: netCDF4 format requested but no cpp-directive __netcdf4 given switch back to 64-bit offset format	netcdf_data_format > 2 has been set. This requires netCDF4 features, which have to be activated by setting the cpp-directive __netcdf4 in the configuration file (%cpp_options). It also requires a netCDF4 library. Set -I, -L and -l options in compile (%compiler_options) and load (%linker_options) options of the configuration file appropriately.

PA0186	no spectra data available	This message occurs if the data_output_spectra routine is called but no spectra data was calculated through the routine calc_spectra. Check your spectra settings in the parameter file.
PA0187	fft method "system-specific" currently does not work on NEC	Usage of system-specific fft has been switched on with parameter fft_method, but the relevant part of the PALM code where the NEC-fft-library calls (e.g. DZFFT or DZFFTM) are used contains bugs which still require to be solved. You may submit a trouble ticket and ask for help.
PA0188	no system-specific fft-call available	You have set fft_method = system-specific. In this case you additionally have to set the cpp-preprocessor switches -D__ibm or -D__nec to specify the fft-library that you like to use. Calls to IBM/NEC-libraries are the only one implemented so far in the PALM code. Probably you forgot to set such a switch. Set the switch and do not forget to recompile the code.
PA0189	fft method "..." not available	See fft_method for the availabe methods that are implemented in PALM and modify the initialization-parameter fft_method in your NAMELIST file appropriately.
PA0190	flow_statistics is called two times within one timestep	Routine flow_statistics computes average profiles and further average flow quantities. It is only allowed to call this routine once during a time step (one timestep consists of several intermediate steps due to the selected time integration scheme). Please submit a trouble ticket if you have run into this error.

PA0192	timestep has exceeded the lower limit dt_1d = ... s simulation stopped!	The time step of the 1D model is determined according to the diffusion criterion to assure a stable numerical solution. This error message means that the required minimum time step is several orders of magnitude smaller than dt_max_1d. The error message may indicate for unrealistic settings of e.g. boundary conditions or other NAMELIST parameters. Please also check if this error appears if you run without USERCODE. To compile and run the PALM and USERCODE with DEBUG-options might also give sometimes valuable hints.
PA0193	unknown initializing problem	This should not happen during the initialization of the model variables in the routine init_3d_model. Please submit a trouble ticket if you have run into this error.

The grid-dependent mixing length l_grid ( = Δ = (Δx Δy Δz)1/3 ) becomes larger than 2.7 * dx or 2.7 * dy starting from the reported height level k. Although PALM will not abort due to this warning, the chosen grid setup might lead to untrustworthy results. The reason for this is an unfavourable choise of grid anisotropy. To avoid this, make sure that the values of dx, dy, and dz do not differ too much from each other. In case of grid stretching, the settings of dz_stretch_level and/or dz_stretch_factor should be changed to ensure a smaller difference between dz(k) and dx and dy at the reported height level.

Due to canyon_width_x the setup of the single street canyon (topography = 'single_street_canyon' ) yields a too narrow canyon or the canyon walls are outside of the model domain. Please check the canyon parameters in your parameter file.
PA0206	inconsistent canyon parameters:... cys=... cyn=... cwy=... ch=... nx=... ny=...	Due to canyon_width_y the setup of the single street canyon (topography = 'single_street_canyon' ) yields a too narrow canyon or the canyon walls are outside of the model domain. Please check the canyon parameters in your parameter file.

PA0225	x-direction: gridpoint number (...) is not an integral multiple of the number of processors (...)	The division of the number of grid points along the x-direction given by nx+1 by the number of processors along the x-direction has a rest and is therefore not an integral multiple of the number of processors. To solve this problem you must ensure that the aforementioned division is without rest for example by setting the number of PEs in x-direction manually (see npex) or by changing nx. It might also be the case that you did not think about that nx+1 is the total number of gridpoints along the x-direction instead of nx.
PA0226	Each dz_stretch_level_start has to be ... than ...	The stretching region has to be defined above the first two grid points (Prandtl-layer). In case of ocean mode the stretching region muss below the two highest grid points (surface). Please adjust dz_stretch_level_start accordingly.

The division of the number of grid points along the y-direction given by ny+1 by the number of processors along the y-direction has a rest and is therefore not an integral multiple of the number of processors. To solve this problem you must ensure that the aforementioned division is without rest for example by setting the number of PEs in y-direction manually (see npey) or by changing ny. It might also be the case that you did not think about that ny+1 is the total number of gridpoints along the y-direction instead of ny.
PA0228	Two adjacent values of dz must be different	It is necessary to specify different values for dz if they are adjacent.
PA0229	nesting-setup requires different number of MPI procs (...) than provided (...)	This message appears for nested runs, if the total number of MPI processes for all nested domains given in the nestpar-NAMELIST is larger than the number of MPI processes which has been allowed for the run, e.g. with palmrun-option -X. (Attention: For hybrid OpenMP/MPI-runs the number of MPI processes allowed for the run is the number given by -X divided by the number of threads per MPI-task, as given with palmrun-option -O.) You either have to provide the run more resources (i.e. more cores) or you have to decrease the number of MPI processes in $nestpar.
PA0230	transposition z --> x: nz=... is not an integral multiple of pdims(1)= ...	Due to restrictions in data transposition, the division of nz by the number of processors in x-direction has to be without rest.

PA0231	transposition x --> y: nx+1=... is not an integral multiple of pdims(2)= ...	Due to restrictions in data transposition, the division of nx+1 by the number of processors in y-direction has to be without rest.

PA0235	mg_switch_to_pe0_level out of range and reset to 0	mg_switch_to_pe0_level was manually set out of range. It was reset to 0, so that the gathering level is determined automatically and displayed in file RUN_CONTROL. See mg_switch_to_pe0_level for details.
PA0236	grid coarsening on subdomain level cannot be performed	The multigrid pressure solver halfs the number of grid points in each direction to get coarser grid levels. This is done for the subdomains on each PE until one of the directions cannot be divided by 2 without rest. If this is the case, the coarsest grid level of each subdomain are gathered on each PE for further coarsening. Before gathering, the coarsening must be done for the subdomain at least one time. You get this error messages for example with the following combination: nx = 60, ny = 60, nz = 60, npex = 4, npey = 2. With this combination, the subdomain on each PE has the size: nx = 15, ny = 30, nz = 60. The number of grid points in the x-direction of the subdomain cannot be divided by 2 and no coarsening is possible for the subdomains in this example. To avoid this error ensure that the number of grid points in each direction can be divided by 2 without rest on the subdomain of an PE at least one time. Therefor vary the number of grid points for the direction which does not fit by changing nx , ny or nz or adjust the number of processors by modifying the parameters npex or npey in order to get other subdomain sizes. In the example given above, you can avoid the error by changing nx or npex. For example setting nx = 64 leads to a subdomain of nx = 16, ny = 30, nz = 60. All numbers are now divisible by 2 without rest and the first coarser grid on the subdomain is then: nx = 8, ny = 15, nz = 30.
PA0237	multigrid gather/scatter impossible in non parallel mode	You are using the multigrid-solver and are running PALM in non-parallel mode (i.e. on a single processor core), but you have set a multigrid level (using parameter mg_switch_to_pe0_level) from where on data shall be collected on core 0 in order to allow for a further coarsening of the grid. Obviously, this does not make sense if only one core is used. Remove this parameter from your NAMELIST-file or set it to value -1 to switch of collection.
PA0238	more than 10 multigrid levels	You have selected the multigrid Poisson-solver (psolver = "multigrid") and a numerical grid which allows for more than 10 coarsening levels. This may happen for very large grids where the grid point numbers along x,y,z are given by 2n with n>10. The smallest grid which may cause this error would have 20483 points. However, depending on the chosen domain decomposition, much larger grids might be possible. Choose a different number of grid points to circumvent this problem.

PA0283	no sufficient convergence within 1000 cycles	Still after 1000 cycles of the multigrid-solver the divergence residual is larger than the residual limit given by residual_limit. Try to increase the residual limit, or fix the number of multigrid cycles (see mg_cycles). In any case, carefully check if the divergence of the velocity field is sufficiently reduced by the multigrid solver. This can be done by comparing the divergence before and after the call of the multigrid solver which is printed in the RUN_CONTROL file. If this error appears during the initial phase of a run (before the first timestep), the number of subdomain gridpoints along x/y/z probably do not allow sufficient coarsening of the grid. The number of gridpoints should allow for a division by two (without rest) at least 2-3 times.

See documentation of tubulent inflow for detailed information on the use of restart data for precursor runs.
PA0309	inflow profiles not temporally averaged. Averaging will be done now using ... samples.	The tubulent inflow method needs time averaged inflow profiles. This warning occurs if the output of time averaged profiles (skip_time_dopr + dt_dopr) is not an integral divisor of the end_time which is specified for the precursor run or if skip_time_dopr + dt_dopr is larger than this end_time.
PA0310	remote model "..." terminated with terminate_coupled_remote = ... local model "..." has terminate_coupled = ...	The remote model in a coupled run has been terminated. The reason for the termination is provided by terminate_coupled. Termination reasons: 1 model was terminated (unknown reason) 2 time step has reached minimum limit (see PA0312) 3 run will be terminated because it is running out of job cpu limit remaining time (see PA0163) 4 run will be terminated due to user settings of dt_restart (see PA0164) 5 run will be terminated due to user settings of restart_time (see PA0164) 6 unscheduled termination was forced by the user (see PA0398)
PA0311	number of gridpoints along x or/and y contain illegal factors only factors 2, 3, 5 are allowed	In case that fft_method='temperton-algorithm', the number of horizontal grid points (nx+1, ny+1) must be composed of prime factors 2,3 and 5. Higher prime factors such as 7 are not allowed. Please ensure that these restrictions are fulfilled or use 'singleton-algorithm' as fft_method.

The time step is determined according to the CFL criterion to assure a stable numerical solution. This error message means that the required minimum time step, determined from the three velocity components, is several orders of magnitude smaller than dt_max, or, in other words, that at least one of the velocity components got too large. Due to the large number of complex reasons it should be noted that this list is not complete, but it is intended to give general hints how to proceed in case of this error message. First, check for a unrealistic value of dt_max in the NAMELIST file. Moreover, this error message may indicate for unrealistic settings of e.g. boundary conditions or other NAMELIST parameters. For very small vertical grid spacing dz this error might also occur if roughness_length >= dz. Please also check if this error appears if you run without USERCODE. To compile and run the PALM and USERCODE with DEBUG-options might also give sometimes valuable hints.
PA0313	Resolved plant-canopy is defined on top of an artificially created building grid point (emerged from the filering) - LAD profile is omitted at this grid point	Due to numerical reasons one-grid point cavities in topography are filtered, so that building geometries might be changed on this scale. In case tall canopy is directly adjacent to the building before, it may happen that building and plant canopy overlap after the filtering. In order to avoid that LAD is mistakenly mapped on top of buildings, which may significantly affect the downstream flow and radiation properties, LAD profiles are ommitted at these artificially-created building grid points.
PA0314	External radiation forcing does not cover the entire simulation time.

Repeat the precurser with the current version or carry out the main run with the same version as the precursor. You can check the svf binary version number which is required for the main run in radiation_model_mod.f90​.
PA0483	Wrong number of SVF or CSF	This error can happen if svf data is read from file SVFIN (e.g. during manual restarts). The local number of sky view factors and canopy sink factors for calculating surface reflection of radiation has to be the same between the precursor run and the main run. Be sure that you create the svf binary data with the same version as the version of the main run.
PA0484	The lowest level where vertical stretching is applied have to be greater than ...	The wind turbine model implemented in PALM does not consider a stretched grid. Therefore grid stretching should only be applied well above the region where the wind turbine model is active. Please adjust dz_stretch_level_start accordingly.

Change nz in your parameter file, or choose psolver = 'multigrid_noopt' (but be aware that with an uneven value of nz the multigrid solver can only use one grid level, so you will have no multi grid levels at all and hence convergence will be very low!).
PA0496	The lowest level where vertical stretching is applied have to be greater than ...	The radiation model does not consider a stretched grid. The assumption of a uniform grid is necessary in parts below the top layer of urban surface (index height nzut). Please adjust dz_stretch_level_start accordingly.

PA0503	z0 exceeds surface-layer height at horizontal/vertical natural/urban surface and is decreased appropriately	In PALM, Monin-Obukhov similarity is assumed between the surface and the first computational grid point normal to the surface. Because of the staggered grid, the distance between these two points is half of the grid spacing in the respective direction, i.e. dz/2 in vertical direction. The height z = dz/2 defines the top of the (analytical) logarithmic layer zs, which is called the surface layer height here. Now functions like ln(zs/z0), where z0 is the roughness length, are used to calculate characteristic surface layer variables like u* or theta*. This mathematically requires that zs > z0, or in other words, that z0 < dz/2. In case you have run into this error, you either need to reduce the roughness length z0 or increase the grid spacing dz. Attention: This message is given only once (for the first grid point where the exceedance has been detected). Be aware that there might be more grid points where z0 exceeds the surface-layer height.
PA0504	A mixture of different LOD for the provided boundary data is not possible.	In case of mesoscale nesting (see nesting_offline) the boundary data can be provided as level-of-detail (LOD) 1 or as LOD 2. However, a mixture of both in one simulation is not possible.

You should try to adjust the number of subdomain grid points in a way that each of (nx+1)/npex, (ny+1)/npey, and nz contain power-of-two (2n) factors with at least n = 2 or larger. Be aware that you can change both, the total number of gridpoints of the total domain, and/or the number of PEs. Alternatively, in case that you cannot change your grid or virtual processor grid, you may try to increase the number of Gauss-Seidel iterations (ngsrb) to improve convergence, but this approach is very limited.

PA0661	namelist file "PARIN" or "PARIN_O" not found! Please have a look at the online description of the error message for further hints.	The origin of this error can have several reasons. Most likely, the activation string of the palmrun command was incorrect. You have to assure that the correct activation string is set so that the parameter namelist is recognised by palmrun (per default, this is 'd3#' for normal runs or 'd3r' for restarts). If you use several strings within the list of activation strings, make sure that each string is separated by a blank, i.e. do not write 'd3#restart' but 'd3# restart'. If you used a modified version of .palm.iofiles, there is probably an incorrect linkage between the PARIN file and the actual file inside the INPUT directory. Please refer to the documentation of palm_iofiles for how to correctly configure this file.

If you specified any data-output quantity for a xy-, xz-, or yz-cross section via data_output, then you need to also specify the location of at least one corresponding cross section via section_xy, section_xz, or section_yz.
PA0684	Found building surface on non-building coordinates (xs, ys, zenith, azimuth): "xs, ys, zenith, azimuth"	If the variable building_surface_pars has been specified within a static driver, the coordinates xs/ys/zs define the location of a horizontal/vertical buildings surface, while zenith/azimuth define the orientantion of the surface (upward-, northward-, southward-, eastward-, westward-facing). In case this error message appears, the coordinates xs, ys, zs, zenith, and azimuth describing a surface element do not match with the location of a building. Even if xs, ys, zs, are prescribed correctly, mismatches in zenith and azimuth may cause this error. In such a case, please check carefully your pre-processor code that you used to create the static driver. Further information about the data input for surface elements can be found here.
PA0686	The relative material fractions do not sum-up to one at horizotal/vertical surface. (i,j) = ...	If building_pars is specified within a static input file, all parameters indicating the relative fraction of wall / window / green surfaces must be given.

PA0697	The mixing ratio exceeds the saturation mixing ratio	The mixing ratio must not exceed its saturation mixing ratio by more than 2 percent. Higher values are physically unrealistic and will not be observed in the atmosphere. In case cloud physics are considered, oversaturation would create strong convection leading to unpredictable model behavior. Further, oversaturated mixing ratios have implications in the land-surface model, where moisture might condense immediately at the surface, creating very high surface fluxes. Note, an error message is given in the initial run, while only a warning is given when moisture exceeds its saturation value in a restart run.
PA0698	Unclassified surface element at grid point (k,j,i) =	Input data is not defined consistently. Please contact the Palm support.
PA0699	Bottom and top boundary are treated equal	This is just an informative message. It tells you that the regions close to the bottom and top boundaries are treated physically and numerically equal. This is not necessarily the case for normal atmospheric runs.
PA0700	dz should be equal close to the boundaries due to symmetrical problem	To get realistic results of a closed channel flow, it is necessary to treat bottom and top boudary region the same. This includes the grid spacing.
PA0701	A constant flux layer is not allowed if a closed channel shall be used	So far, the constant flux layer approach is only implemented for the bottom boundary but bottom and top boundary shall be treated equal for closed channel flows. Therefore, it is not allowed.

Solution: Make sure that ncols matches nx+1 and that nrows matches ny+1.
PA0705	If virtual measurements are taken, the number of surrounding grid points must not be larger than the number of ghost points - 1	When virtual measurements are taken, data is sampled at given station grid coordinates. It is possible that also the adjoining grid points can be sampled, however, the number of grid points additionally sampled in each direction must not be larger than the number of ghost points - 1 to avoid any segmentations faults. In the future we will improve this to allow a more flexible number of offset grid points.

NC****	**** contains numbers in the range from 1-521	Internally, PALM calls the netCDF function NF90_STRERROR which returns an error message string provided by netCDF. Hence, no exact assignment between PALM error number and netCDF error string can be given. Most of the netCDF errors should never appear if the default code is used. The following list gives errors which may be caused by wrong steering or errors due to problems in the user interface.
NC0079	String match to name in use	A netCDF variable name has been used twice. Possible reasons: a variable in the parameter file has been listed twice (e.g. in data_output) or a variable name that has been defined in the user interface is already used by PALM.
NC0253	Name contains illegal characters	netCDF variable names consist of arbitrary sequences of alphanumeric characters. These names are e.g. assigned by the user in the user-interface to variables dots_label or dopr_label. Due to the netCDF convention, they must not start with a digit. Also, usage of / as special character is not allowed. Older netCDF versions (before 3.6.3) have further restrictions on special characters. Please check if your string settings in the user-interface follow the above rules.
