NOTE: We now post results from 1-year GEOS-Chem benchmark simulations on the GEOS-Chem wiki.
(Bob Yantosca, 16 Jan 2014)

For each GEOS-Chem 1-year benchmark simulation, we create a series of plots displaying 3 model versions simultaneously against observations. The models are plotted with red, green, and blue symbols, and the observations are plotted as black symbols.

The table below lists which models are displayed for each 1-year benchmark simulation. Click on a particular model version (under the "Benchmark" column) to view the output plots in PDF format.

Also be sure to see our wiki page where we track the evolution of the mean OH diagnostic in the various GEOS-Chem 1-year benchmark simulations.
