    55Input 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 supplement _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 supplement _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. 
     6The static input file, indicated by the filename suffix _STATIC, contains all static information, such as topography, geographical latitude and longitude, surface and vegetation information.
     7The dynamic input file, indicated by the filename suffix _DYNAMIC, contains dynamic information on the initial state of the atmosphere or time-dependent boundary conditions.
     8The radiation input file, indicated by suffix _RAD, contains static and dynamic information on radiation properties such as trace gas profiles or sky-view factors.
     9The chemistry input file, indicated by suffix _CHEM, contains static and dynamic information on chemical species and emissions.

    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.

    1515After reading the input files, PALM-4U performs consistency checks on the provided data.

    2222The 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 variable in the static input file.
     23The 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.
    2424In 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.
    2525In a second step, surfaces are initialized individually by providing the bulk classification at each grid point individually.
