NOTES:
- GEOS-1 and GEOS-STRAT are now obsolete and no longer supported by GEOS-Chem
- GEOS-3 is still supported but we recommend users to migrate to GEOS-4 or GEOS-5.
- MERRA data will be made available at 4 x 5 resolution in the near future. MERRA is a long-term reanalysis done with version GEOS-5.2.0.
