    3838A main factor influencing atmospheric chemistry are the emissions of reactive compounds. In PALM4U emissions can be applied in three different ways:\\
    39     * 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 beow. No other emissions are considered. street_type can be obtained from Openstreetmap.\\
     39    * 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.\\
    4040    * 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.\\
    41     * PREPROCESSED: Preprocessed hourly (other temporal intervals will be possible in later versions) 3-d emission fields must be supplied by the user.
    42    
     41    * PRE-PROCESSED: Preprocessed hourly (other temporal intervals will be possible in later versions) 3-d emission fields must be supplied by the user.
     42
     43Importantly, 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.

    4445Chemistry is automatically activated when a {{{chemistry_parameters}}} namelist is set in the parameter file ({{{_p3d}}}).
