v68 v69 4 4 5 5 Input variables are distinguished between [#static_input static], [#dynamic_input dynamic], [#rad_input radiation] and [#chem_input chemistry] input variables, while for each a separate input file exists. 6 The static input file, indicated by the filename su pplement_STATIC, contains all static information, such as topography, geographical latitude and longitude, surface and vegetation information.7 The dynamic input file, indicated by the filename su pplement_DYNAMIC, contains dynamic information on the initial state of the atmosphere or time-dependent boundary conditions.8 The radiation input file, indicated by _RAD, contains static and dynamic information on radiation properties such as trace gas profiles or sky-view factors.9 The chemistry input file, indicated by _CHEM, contains static and dynamic information on chemical species and emissions.6 The static input file, indicated by the filename suffix _STATIC, contains all static information, such as topography, geographical latitude and longitude, surface and vegetation information. 7 The dynamic input file, indicated by the filename suffix _DYNAMIC, contains dynamic information on the initial state of the atmosphere or time-dependent boundary conditions. 8 The radiation input file, indicated by suffix _RAD, contains static and dynamic information on radiation properties such as trace gas profiles or sky-view factors. 9 The chemistry input file, indicated by suffix _CHEM, contains static and dynamic information on chemical species and emissions. 10 10 11 11 An example NCL-script to create a simple [[attachment:example_static|static input file]] can be found 12 12 [[attachment:example_driver_static.ncl|here]]. 13 To create a dynamic driver, PALM-4U provides the pre-processing tool [#inifor inifor], which extracts 1D/3D initialization data for the soil and atmosphere as well as boundary data for the PALM-4U domain from COSMO output.13 To create a dynamic driver, PALM-4U provides the pre-processing tool [#inifor inifor], which extracts 1D/3D initialization data for the soil and atmosphere as well as boundary data for the PALM-4U domain from DWD-COSMO output. 14 14 15 15 After reading the input files, PALM-4U performs consistency checks on the provided data. … … 21 21 22 22 The static input file encompasses topography information as well as all necessary information file to initialize all land- and urban-type surfaces in the model, such as heat capacities, roughness, albedo, emissivity, etc.. 23 The initialization procedure for the surfaces follows a multi-step approach, depending on the given level of detail of each provided variablein the static input file.23 The initialization procedure for the surfaces follows a multi-step approach, depending on the given level of detail of each variable as provided in the static input file. 24 24 In a first step, surfaces are initialized horizontally homogeneous with a bulk classification for each type (e.g. vegetation or soil), either set by a default value or set by a namelist-provided value, while the bulk classification provides standard values for a variety of parameters. 25 25 In a second step, surfaces are initialized individually by providing the bulk classification at each grid point individually.
