    1717Currently PALM-4U includes the following sample of chemistry mechanisms:\\
    18   * cbm4: Carbon Bond Mechanism (Gery et al. 1989, 32 compounds, 81 reactions)\\
     18  * cbm4: Carbon Bond Mechanism (Gery et al. (1989), 32 compounds, 81 reactions)\\
    1919  * smog: Photochemical smog mechanism (13 compounds, 12 reactions)\\
    2020  * simple: Simplified version of SMOG (9 compounds, 7 reactions)\\
     
    3232In order to select and apply a certain mechanism from this sample, please copy the respective ready-to-use `chem_gasephase_mod.f90` from `UTIL/chemistry/gasphase_preproc/mechanisms/def_MECH` (where `MECH` stands for any of the available mechanisms) into the USER_CODE directory of the respective simulation Setup, i.e. .../JOBS/<run_identifier>/USER_CODE/chem_gasphase_mod.f90.

    34 Alternatively, the chemistry preprocessor can be executed also for the available machanism in order to create chem_gasphase_mod.f90 (although for the available mechanisms this is not necessary because the chem_gasphase_mod.f90 files are already existing) instead of copying chem_gasphase_mod.f90: Enter the directory UTIL/chemistry/gasphase_preproc and apply the run script, i.e. {{{run_kpp4palm.ksh -m MECH}}}, where MECH stands for any of the mechanisms listed above. The resulting chem_gasphase_mod.f90 will be copied by the script directly into the SOURCE directory.

    3636In order to find out which reactions and compounds are included in the different mechanisms, please have a look into the files MECH.eqn and MECH.spc in `UTIL/chemistry/gasphase_preproc/mechanisms/def_MECH`.

    38 How to implement a new chemical mechanism or add further passive tracers see the [wiki:chempar#no1 Readme-File]. If more than two passive tracers or different names of the passive tracers are desired, a new 'mechanism' must be created as described in the Readme file. The Readme file is also available in the PALM-4U subdirectory UTIL/chemistry/gasphase_preproc.
    39 
    40 Currently, areosol compounds can be considered either as passive compounds or the sectional aerosol module SALSA [wiki:wiki/doc/app/salsa] (Kokkola et al., 2008 Atmos. Chem. Phys., 8, 2469–2483, 2008) can be used to simulate the aerosol particle concentrations, and size distributions.
