v89 v90 16 16 17 17 Currently 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)\\ 19 19 * smog: Photochemical smog mechanism (13 compounds, 12 reactions)\\ 20 20 * simple: Simplified version of SMOG (9 compounds, 7 reactions)\\ … … 32 32 In 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. 33 33 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.f90will be copied by the script directly into the SOURCE directory.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. 35 35 36 36 In 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`. 37 37 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.38 How to implement a new chemical mechanism or add further passive tracers see the [wiki:chempar#no1 Readme-File].
