GEOS-Chem chemistry mechanisms: Difference between revisions

Revision as of 21:00, 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 PLUS bromine 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

The bromine tracers and species were added to the standard mechanism just prior to the release of GEOS-Chem v9-01-03.
