+
+In PALM-4U emissions can be applied in three different ways:
+
+ • PARAMETERIZED: Traffic emissions are parameterized depending on the the values of street_type in the static file. Emission values for each street type and chemical compound must be supplied in the namelist as described below. No other emissions are considered. street_type can be obtained from OpenStreetMap.
+
+ • DEFAULT: Gridded yearly emissions must be supplied by the user as specified in the PIDS document (see sample emissions file). Typical temporal variations are apllied by PALM4U.
+
+ • PRE-PROCESSED: Preprocessed hourly (other temporal intervals will be possible in later versions) 3-d emission fields must be supplied by the user. 
+
+Importantly, for the DEFAULT and the PRE-PROCESSED mode of the emissions, the exact date of the start of the simulation must be indicated through the namelist parameter date_init of the date_and_time_mod module. 
+
+IMPORTANT: In the PRE-PROCESSED mode the initial date of the simulation has to coincide with the first day for which emission values are available. 
+
+Find a more detailed description of the PALM-4U emission input in the corresponding attached document [https://palm.muk.uni-hannover.de/trac/attachment/wiki/doc/app/chempar/chem_emissions_PALM4U.pdf here].
