    5 SALSA runs with the default parameter values. By default, the aerosol particle and gaseous concentrations are initially constant everywhere ([#isdtyp isdtyp] = 0 and [#igctyp igctyp] = 0). A minimum set of input parameters to be applied when this initialisation type is used, is:
    65
    7 * [#dpg dpg], [#n_lognorm n_lognorm] and [#sigmag sigmag] to describe the initial aerosol size distribution '''plus'''
    8 
    9 * [#listspec listspec], [#mass_fracs_a mass_fracs_a] to include chemical compounds '''plus'''
    10 
    11 * [#H2SO4_init H2SO4_init], [#HNO3_init HNO3_init], [#NH3_init NH3_init], [#OCNV_init OCNV_init], [#OCSV_init OCSV_init] to set the initial concentrations of gaseous compounds '''plus'''
    12 
    13 * [#nlcnd nlcnd], [#nlcndgas nlcndgas], [#nlcndgash2oae nlcndgash2oae], [#nlcoag nlcoag], [#nldepo nldepo], [#nldepo_topo nldepo_topo], [#nldepo_vege nldepo_vege], [#nsnucl nsnucl] to switch on aerosol dynamic processes.
    14 
    15 Alternatively, the initial aerosol particle concentrations, size distributions and chemical compositions and gaseous concentrations as well as emission/source information of aerosol particles and gases can be provided in NetCDF input files {{{<run_identifier>_salsa}}} (for aerosol particles) and {{{<run_identifier>_chemistry}}} (for gaseous compounds). Aerosol particle emissions can be provided applying three levels of detail (LOD): parametrised (LOD1, units kg m^-2^ s^-1^) or detailed (LOD2, units m^-2^ s^-1^) 2-dimensional surface fluxes, or 3-dimensional sources (LOD3, units m^-3^ s^-1^). Gaseous emissions, instead, should currently be specified as gas-specific surface fluxes (LOD2) if the chemistry module is not applied. The time dependency of the aerosol emissions has not yet been implemented. Example files for each LOD is provided in the attached [#test_salsa test_salsa] example set-up.
    16 
    17 The attached test_salsa example includes:
    18     * {{{test_salsa_p3d}}}: ASCII parameter file
    19     * {{{test_salsa_static}}}: NetCDF static-information file with topography information (so-called static driver)
    20     * {{{test_salsa_chemistry}}}: a NetCDF information file including the initial vertical profiles and surface emissions of gaseous compounds (H2SO4, HNO3, NH3, OCNV and OCSV)
    21     * '''LODX_'''{{{test_salsa_salsa}}}: a NetCDF information including the initial vertical profiles and emissions of aerosol particles for each level of detail X = 1, 2, 3. NOTE! Copy the chosen file to {{{test_salsa_salsa}}}
