Overview

This page is part of the Chemistry Model (CHEM) documentation.
It contains a listing of setup examples.
For an overview of all CHEM-related pages, see the CHEM main page.

Example setups

The PALM-4U subdirectory TESTS/cases of the trunk contains some sample setups for different application types. A setup for a very small urban area with the 'phstatp' mechanism can be found in 'urban_environment' and 'urban_environment_restart'.

An example setup with two passive tracers for the small test_urban model domain is attached to this page (attachment test_urban_chem_passive.tar.gz).

A further setup (attachment test_berlin_chem_smog.tar) is attached for 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 the 'smog' mechanism.

Please 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_gasphase_mod.f90, which is supplied in UTIL/chemistry/gasphase_preproc/mechanisms/def_smog into the USER_CODE subdirectory of your JOBS/Name_of_your_setup or into SOURCE (or execute run_kpp4palm.ksh -m smog from the UTIL/chemistry_gasphase_preproc directory).

So 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.
