GEOS-Chem 12 benchmark history
GEOS-Chem v11-02-final will also carry the designation GEOS-Chem 12.0.0. We are migrating to a purely numeric versioning system in order to adhere more closely to software development best practices. For a complete description of the new versioning system, please see our GEOS-Chem version numbering system wiki page.
On this page we have posted complete information about all benchmark simulations (both 1-month and 1-year) for GEOS-Chem 12.
