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

In GEOS-Chem v9-01-03, users could select from one of four pre-defined chemistry mechanisms:

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.
