On this page, we provide information about GEOS-Chem simulations that use chemistry mechanism solver code built by the Kinetic PreProcessor (KPP).
Overview
The following table provides links to information about the available chemistry mechanisms in GEOS-Chem.
We use the KineticPreProcessor (KPP) to generate optimized source code to integrate the chemical mechanism forward in time. For more information about how to modify GEOS-Chem chemical mechanisms, please see our Update chemical mechanisms with KPP Supplemental Guide at geos-chem.readthedocs.io.
