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.
