    99The main routines and the Driver of the chemistry module is included in chemistry_model_mod.f90.

    11 The module chem_gasphase_mod.f90, where the gas phase chemistry rate equations are solved within PALM4U depends on the chosen chemical mechanism. chem_gasphase_mod.f90 is generated by a preprocessor that is based on the Kinetic Pre-Processor KPP (Damian et al., 2002, Sandu et al., 2006), Release 2.2.3 from November 2012 (http://people.cs.vt.edu/asandu/Software/Kpp/, kpp-2.2.3.tar.gz) and an adapted version of the KPP postprocessor KP4 (Jöckel et al, 2010). This adapted Version of kp4 which converts the KPP-generated code to a PALM4U module is named kpp4palm.

    1313Currently PALM-4U includes the following sample of chemistry mechanisms:[[BR]]
     
    1717PHSTAT: Photo-stationary state (3 compounds, 2 reactions)[[BR]]
    1818
    19 Additionally 'mechanisms' are availble that describes the transport of one and two passive tracers 
     19Additionally 'mechanisms' are availble that describes the transport of one and two passive tracers[[BR]]
    2020PASSIVE1: Passive tracers (1 compound, 0 reactions)[[BR]]
    2121PASSIVE: Passive tracers (2 compounds, 0 reactions)[[BR]]
    2222and the mechanisms mentiones above plus one passive Tracer (e.g SIMPLE: Simplified of SMOG plus one Tracer named PM10 (10 compounds, 7 reactions)[[BR]]

    24 For details about preparing chem_gasphase_mod.f90 for a selected mechanism see Readme_KPP4PALM.odt in the PALM4U subdirectory UTIL/chemistry/gasphase_preproc.
     24For details about preparing a chem_gasphase_mod.f90 for  different chemical mechanism than the one that comes with checkout of PALM4U (currently PASSIVE) see Readme_KPP4PALM.odt in the PALM4U subdirectory UTIL/chemistry/gasphase_preproc.

     26Chemistry is automatically activated when a {{{chemistry_parameters}}} namelist is set in the parameter file ({{{_p3d}}}).
