Date	Author	svn Revision	Last Release	Type	Description
21/02/17	FH	r2155	4.0	B	Bugfix: cloud microphysics are now also calculated on ghostpoints (prognostic_equations.f90, microphysics_mod.f90)
17/02/17	LV	r2152	4.0	N, B	New Tip loss correction for the wind turbine parametrization (wind_turbine_model_mod.f90) new control parameter tl_cor (Default=.FALSE.) Bugfix Bugfix in subroutine wtm_read_blade_tables (wind_turbine_model_mod.f90)
09/02/17	KS	r2147	4.0	C, B	Changes improved label bar in palmplot (cross_sections.ncl) added gharbi and kuma to the list of known hosts (subjob) changed allocation of resources for lcbullhh (mrun) Bugfix Land surface parameters II corrected for veg_type 18 and 19 (land_surface_model_mod)
06/02/17	TG	r2141	4.0	C	Changed check for existing files in mrun at the beginning of a run. (mrun)
02/02/17	SR	r2134	4.0	N	Option -E added to msub commands on HLRN-III machines to allow output of more job information in the job protocol files. (subjob)
24/01/17	SR	r2130	4.0	B	In case of nested runs the stop condition in case of too small timesteps is communicated to all parent/child processes. (Makefile, timestep)
20/01/17	MS	r2128	4.0	B	Bugfix, setting of user-defined topography in case of ocean simulations. (init_grid)
20/01/17	SR	r2126	4.0	C	For ocean simulations, density in SGS-TKE-production is replaced by potential density. (production_e)
18/01/17	FH	r2122	4.0	C	A particle ID has been introduced. It is stored on the particle variables id1 and id2. (Creating two IDs is necessary due to the large number of potentially simulated particles.) For this purpose, the unused particles variables tailpoints and tail_id have been renamed. Moreover, the unused particle variable dvrp_psize has been renamed to user and can be used by the user. (lpm_data_output_particles, lpm_init, lpm_set_attributes, mod_particle_attributes) Additionally, the calculation of the equilibrium radius of aerosols has been improved (lpm_init). And the code has been reformatted (lpm_droplet_collision).
17/01/17	SR	r2118	4.0	C	All OpenACC directives and related parts removed from the code (trunk). See the new GPU-porting branch for the OpenACC-GPU version of PALM. (Makefile, advec_ws, boundary_conds, buoyancy, check_parameters, coriolis, cpulog_mod, diffusion_e, diffusion_s, diffusion_u, diffusion_v, diffusion_w, diffusivities, exchange_horiz, fft_xy_mod, flow_statistics, header, init_3d_model, modules, palm, parin, poisfft_mod, pres, production_e, prognostic_equations, surface_layer_fluxes_mod, swap_timelevel, time_integration, timestep, transpose, tridia_solver_mod, wall_fluxes, deleted: cuda_fft_interfaces_mod)
16/01/17	BM	r2116	4.0	N	Beta version of new tool palm_gf added. palm_gf allows to calculate all possible processor grids. A detailed description will follow.
12/01/17	FK	r2114	4.0	N	cpp switch __mpi3 added for MPI-3 standard code. (urban_surface_mod) This was necessary because some older compiler versions cannot handle MPI-3 operations, hence, respective parts of the code shall only be compiled if explicitly enabled by the cpp switch __mpi3. However, the urban surface model only works with these MPI-3 operations included.
09/01/17	FK	r2108	4.0	C	Preparation for doxygen comments. (modules)
05/01/17	MS	r2100	4.0	B	Bugfix: Prevent extremely large SGS-velocities by limiting TKE in stochastic terms. (lpm_advec) Copyright update. (all source-code files)
