NOx-Ox-hydrocarbon-aerosol chemistry
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 | Solvers |
---|---|---|
standard |
|
SMVGEAR, KPP |
SOA |
|
SMVGEAR, KPP |
Dicarbonyls |
|
SMVGEAR only |
isoprene |
|
SMVGEAR, KPP |
All of these mechanisms (with the exception of the dicarbonyls simulation) are compatible with both the SMVGEAR solver and the KPP solver. The dicarbonyls mechanism only works with SMVGEAR.
Prior to the release of GEOS-Chem v9-01-03, several new bromine tracers and species were added to the s
