Mean OH concentration

On this page we track the evolution of the mean OH concentration in GEOS-Chem. This value is an indicator of how "hot" the chemistry is. Please also see the related topic about the methyl chloroform lifetime in GEOS-Chem.

Evolution of mean OH in GEOS-Chem

Plot of mean OH evolution

Here is a plot of the mean OH concentration from GEOS-Chem 1-year benchmark simulations through version 12.8.0 (released 04 May 2020). The mean OH is an indicator how the chemistry mechanism is performing. Typical values are 10–12 x 10⁵ molecules cm^-1.
