 Emissions of gases and/or passive compounds can be provided by the user in different levels of detail (LOD). Three modes were implemented.
-Two modes require emission data from file. Gridded emission information can be provided in two LODs via a netCDF file (see PALM Input Data Standard [[attachment:wiki:doc/app/iofiles/pids:PALM_input_data_standard_v1.12.pdf|(PIDS)]]):

 In a third mode traffic emissions are parameterized on the basis of the street type classification provided by Open Street Map ([https://www.openstreetmap.org]) and street type specific emissions factors. This option, named ’Parameterized’ mode, is currently only implemented for the traffic sector:
 
- • LOD 0 requires a mean surface emission per day (in micromol/m2/d for gases and in kg/m2/d for particulate matter) for each desired species contained in the applied chemical mechanism together with a weight differing between main and side road emissions defined in the PALM Fortran namelist file (see also [wiki:doc/app/par Fortran namelist file] and [wiki:doc/app/iofiles/chemistry_parameters chemistry parameters]). Furthermore, the street type classification provided by Open Street Map must be included in the PALM static driver (see also [wiki:doc/app/iofiles/pids/static here])

 To account for the temporal distribution of the parameterized traffic emissions a diurnal profile based on urban traffic counts is implemented to disaggregate the total emission of the different species to hourly values. Currently, the applied temporal profile is the same for all species and main and side roads.
