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. The mean OH is an indicator how the chemistry mechanism is performing. Typical values are 10–12 x 105 molecules cm-1.
