 The main routines and the driver of the chemistry module is included in chemistry_model_mod.f90. The main routines and the driver of the chemistry module is included in chemistry_model_mod.f90, subroutines are in chem_gasphase_mod.f90, chem_photolysis_mod.f90, and chem_emissions.f90.
 
-The module chem_gasphase_mod.f90, where the gas phase chemistry rate equations are solved within PALM4U depends on the chosen chemical mechanism. chem_gasphase_mod.f90 is generated by a preprocessor that is based on the Kinetic Pre-Processor KPP (Damian et al., 2002, Sandu et al., 2006), Release 2.2.3 from November 2012 (http://people.cs.vt.edu/asandu/Software/Kpp/, kpp-2.2.3.tar.gz) and an adapted version of the KPP postprocessor KP4 (Jöckel et al, 2010, https://www.geosci-model-dev.net/3/717/2010/). This adapted Version of kp4 which converts the KPP-generated code to a PALM4U module is named kpp4palm.

+A main factor influencing atmospheric chemistry are the emissions of reactive compounds. In PALM4U emissions can be applied in three different ways:\\
     * PARAMETERIZED: Traffic emissions are parameterized depending on the the values of street_type in the static file. Emission values for each street type and chemical compound must be supplied in the namelist as described beow. No other emissions are considered. street_type can be obtained from Openstreetmap.\\
     * DEFAULT: Gridded yearly emissions must be supplied by the user as specified in the PIDS document (see sample emissions file). Typical temporal variations are apllied by PALM4U.\\
