Since Version 5.0 a chemistry model is available in PALM which computes chemical conversion and tranport of reactive trace gases. In addition, this module permits also the simulation of passive compounds in the gas phase and particulate matter. 

The chemistry model is automatically activated when a {{{chemistry_parameters}}} namelist is included in the parameter file ({{{<run_identifier>_p3d}}}).
