== [=#testsetups Example setups] ==

The PALM-4U subdirectory TESTS/cases contains some sample setups for different application types. An 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).  

Further setups are 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 for two chemistry settings:
 two passive compounds ('passive')\\ 
 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_gashase_mod.f90}}}, which is supplied in {{{UTIL/chemistry/gasphase_preproc/mechanisms/def_smog}}} into {{{SOURCE}}} (or execute {{{run_kpp4palm.ksh -m smog}}}). 

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.
