GEOS-Chem versions
Here we have posted links to a separate wiki page describing each GEOS-Chem model version.
GEOS-Chem development history
In the sections below, we list information about current and past GEOS-Chem releases.
NOTES:
- Information about 1-year benchmark simulations can be found on the individual wiki pages for each GEOS-Chem version listed below.
- For versions prior to v7-04-12, please see the GEOS-Chem version history web page.

Previously released GEOS-Chem versions
NOTE: Each new GEOS-Chem version since v9-01-02 is now evaluated with one or more 1-year benchmark simulations prior to release. Therefore, each new GEOS-Chem version is now equivalent to what we used to call a "public release" prior to v9-01-02. We have since stopped using the terms "public release" and "beta release".

Mean OH from GEOS-Chem 1-year benchmark simulations
Here is a plot of the mean OH concentration from several recent GEOS–Chem 1-year benchmark simulations. The mean OH is an indicator how the chemistry mechanism is performing. Typical values are 10–12 x 105 molecules cm-1.
