Version history summary

Past releases Current release: GEOS-Chem 12.9.3 Future releases

The sections below describe each GEOS-Chem feature version and GEOS-Chem bug fix patch version belonging to the GEOS-Chem 13 series. Each feature version carries the tag 13.Y.0, which indicates that the version will be (or has been) validated with a 1-month benchmark simulation (and one or more 1-year benchmark simulations if necessary). Each patch version carries the tag 13.Y.Z, which denotes that the version preserves backwards-compatibility with the prior feature version 13.Y.0. For more information, please see our GEOS-Chem version numbering system wiki page.
