Obsolete.jpg

NASA/GMAO ceased production of GEOS-5.2.0 data as of June 2013. See GMAO's GEOS Near-Real Time Data Products page for more details. We recommend that you use either GEOS-FP, which is the current operational GMAO met data product, or MERRA-2, which is the current GMAO reanalysis product. GEOS-5 was de-supported in GEOS-Chem v11-02.

On this page we list the GMAO GEOS-5.2.0 met fields that are currently archived for use with GEOS-Chem. This is only a subset of the entire GEOS-5 met field data archive.

For the latest information about GEOS-5, please consult the following GEOS-5 resources:

  • All A-3 fields are 2-dimensional (lon,lat)
  • The Collection is the name of the GEOS-5.2.0 "raw" data file that a particular data field may be found in. This is specified in the GEOS-5.2.0 file specification document.
