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 |
|---|---|---|---|
| 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.
