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.
