GEOS-Chem v9-02
NOTE: In light of our new benchmarking procedure instituted at IGC5, every GEOS-Chem version released to the user community is now a public release, in the sense that we run a 1-year benchmark before making the code available. The 1-month benchmarks now replace what we used to call "beta releases". This allows us to retire the last two numbers in the version name. We shall henceforth denote GEOS-Chem versions as GEOS-Chem v9-02, etc. instead of using the previous nomenclature (e.g. GEOS-Chem v9-01-03).
