    v79 v80  
    2424  * smog: Photochemical smog mechanism (13 compounds, 12 reactions)\\
    2525  * simple: Simplified version of SMOG (9 compounds, 7 reactions)\\
    26   * simplep: SIMPLE plus one tracer named PM10 (10 compounds, 7 real reactions plus one dummy 'reaction')\\
     26  * simplep: 'simple' plus one tracer named PM10 (10 compounds, 7 real reactions plus one dummy 'reaction')\\
    2727  * phstat: Photo-stationary state (3 compounds, 2 reactions)\\
     28  * phstatp: Photo-stationary state plus one passive tracer named PM10 (4 compounds, 2 real reactions plus one dummy 'reaction')\\

    2930Additional 'mechanisms' are available that describe the transport of one or two passive tracers, i.e. no chemical reactions are necessary:\\
     
    3233This list will be extended further in the future.

    34 In order to select and apply a certain mechanism from this sample, please copy the repctive 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.
    35 
    36 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 directly into the SOURCE directory.
     35The standard mechanism which is in the SOURCE directory is 'phstatp'.

The resulting chem_gasphase_mod.f90 will be copied by the script directly into the SOURCE directory.

    3841In 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`.

    40 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.

    4245Currently, 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.

    571 Test setups are attached here for the small test_urban setup with two passive compounds and a 1km x 1km model domain with 10 m grid width, which is centered around the Ernst-Reuter-Platz in Berlin. For this domain, example input files are supplied for two chemsitry settings:
     574Test setups are attached here for the small test_urban setup with two passive compounds and a 1km x 1km model domain with 10 m grid width, which is centered around the Ernst-Reuter-Platz in Berlin. For this domain, example input files are supplied for two chemistry settings:
    572575 two passive compounds ('passive')\\
    573576 the 'smog' mechanism\\
    574577
    575 Please note that PALM-4U comes by default with the code for two passive tracers, i.e. {{{chem_gashase_mod.f90}}} is prepared for 'passive'. In order to run PALM-4U with the 'smog' mechanism, copy the {{{chem_gashase_mod.f90}}}, which is supplied in {{{UTIL/chemistry/gasphase_preproc/mechanisms/def_smog}}} into {{{SOURCE}}} (or execute {{{run_kpp4palm.ksh -m smog}}}.
     578Please note that PALM-4U comes by default with the code for the photostationay equilibrium between NO, NO2 and O3 plus one passive tracer, i.e. {{{chem_gashase_mod.f90}}} is prepared for 'phstatp'. In order to run PALM-4U e.g. with the 'smog' mechanism, copy the {{{chem_gashase_mod.f90}}}, which is supplied in {{{UTIL/chemistry/gasphase_preproc/mechanisms/def_smog}}} into {{{SOURCE}}} (or execute {{{run_kpp4palm.ksh -m smog}}}.

    577580So far, all example setups are supplied for 'PARAMETERIZED' emissions. Example emissions files for 'PREPROCESSED' and 'DEFAULT' emissions will be supplied here at a later time.
