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

|
Dicarbonyls |

Dicarbonyls |
|

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 chemistry mechanisms that shipped with GEOS-Chem v9-01-03.
The existing
