GEOS-Chem chemistry mechanisms: Difference between revisions

Revision as of 20:57, 30 September 2013

On this page, we provide an overview of the chemistry mechanisms used in GEOS-Chem.

The standard NOx-Ox-hydrocarbon-aerosol (aka "full-chemistry") simulation has undergone several updates in recent GEOS-Chem versions. We

In GEOS-Chem v9-01-03, users could select from one of four pre-defined chemistry mechanisms:

Mechanism	Description	Nickname	Solvers
standard	NOx-Ox-hydrocarbon-aerosol species	Full-chemistry or fullchem	SMVGEAR, KPP
SOA	NOx-Ox-hydrocarbon-aerosol species PLUS secondary organic aerosol species	SOA	SMVGEAR, KPP
Dicarbonyls	NOx-Ox-hydrocarbon-aerosol species PLUS dicarbonyl species	Dicarbonyls	SMVGEAR only
isoprene	NOx-Ox-hydrocarbon-aerosol species PLUS isoprene oxidation products	Caltech isoprene scheme, Paulot isoprene scheme	SMVGEAR, KPP

Prior to the release of GEOS-Chem v9-01-03, several new bromine tracers and species were added to the standard mechanism.
