NASA/GMAO ceased production of GEOS-5.2.0 data as of June 2013. Therefore, you will not be able to use GEOS-5.2.0 met fields to run GEOS-Chem global or nested grid simulations for model dates after June 2013. But you can still run GEOS-Chem simulations using our archive of GEOS-5.2.0 meteorology for years 2004 through mid-2013.

The current GMAO met data product is now the GEOS-FP operational product, which will is supported in GEOS-Chem v9-02 and higher versions. We are processing GEOS-FP data for 2012 up to present day. You will be able to use GEOS-FP for both global and hi-res (0.25° x 0.3125°) nested-grid simulations starting with GEOS-Chem v9-02.

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:

A-3 Fields

  • These are 3-hr time-averaged fields.
  • Data times: 01:30, 04:30, 07:30, 10:30, 13:30, 16:30, 19:30, 22:30 GMT
  • 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.
