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

Overview
NOx-Ox-hydrocarbon-aerosol chemistry and variants
The NOx-Ox-hydrocarbon-aerosol (aka "full-chemistry") simulations have undergone several updates in recent GEOS-Chem versions. We provide a summary of recent updates made to the various mechanisms.
Mechanisms in GEOS-Chem v9-01-03 and prior versions
In GEOS-Chem v9-01-03, users could select from one of four pre-defined chemistry mechanisms:
| Mechanism | Description | Nickname | Solvers |
|---|---|---|---|
| standard |
|
Full-chemistry or fullchem |
|
| SOA |
|
SOA |
|
| Dicarbonyls |
|
Dicarbonyls |
|
| isoprene |
|
Caltech isoprene scheme, Paulot isoprene scheme |
|
The bromine tracers and species were added to the standard mechanism just prior to the release of GEOS-Chem v9-01-03.

Mechanisms in GEOS-Chem v9-02 and later versions
Several modifications were made to the above-mentioned chemistry mechanisms in GEOS-Chem v9-02, as listed below:
| Mechanism | Description | Nickname | Solvers |
|---|---|---|---|
| standard |
|
Full-chemistry or fullchem |
|
| SOA |
|
SOA |
|
| Dicarbonyls |
|
Dicarbonyls |
|
Starting with v9-02, family tracers (NOx, Ox) have now been removed from all GEOS-Chem mechanisms. The individual family members (NO, NO2, O3, etc.) are now carried as individual advected tracers and chemical species. Also, the isoprene mechanism from v9-01-03 now has been folded into the standard mechanism.
