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 full-chemistry mechanisms in GEOS-Chem.

Mechanism	Description	Mechanism file	Extra options
fullchem	NOx + Ox + Br + Cl + I + aerosols chemistry in the troposphere and stratosphere	KPP/fullchem/fullchem.eqn	benchmark complex SOA complex SOA + SVPOA TOMAS APM RRTMG Aciduptake Marine POA
Hg	Mercury chemistry Introduced in 13.4.0 as a KPP mechanism	KPP/Hg/Hg.eqn
carboncycle	KPP/carboncycle/carboncycle.eqn Will debut in 14.1.0 as a KPP mechanism
