== Overview ==

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. 
This documentation contains several sections:
 INPUT:: List of all namelist parameters that can be used to steer the CHEM\\\\ 
 OVERVIEW:: Description of CHEM including the aerosol compounds, deposition and emission\\\\
 CHEMISTRY MECHANISM:: List of all chemistry mechanism currently used in PALM-4U\\\\
 OUTPUT STEERING:: Output of chemistry variables\\\\ 
 INPUT STEERING:: Description of the use of initial concentration and initial vertical profiles in PALM-4U \\\\
 EXAMPLE SETUPS:: Files to carry out example runs using the CHEM \\\\

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