Revision as of 18:24, 21 October 2013

GEOS-FP (formerly named GEOS-5.7.2) is the latest update of the GEOS-5 met data product. It has finer native horizontal resolution (0.25° lat x 0.3125° lon) and temporal resolution (hourly data and 3-hourly data) than older GMAO met products such as GEOS-5, the MERRA reanalysis, and GEOS-4.

NOTE: GEOS-Chem only uses a subset of the entire GEOS-FP data archive. On this page we list the GEOS-FP met fields that archive for use with GEOS-Chem.

For more information, please see:

  1. GEOS5-FP file specification document, Version 1.0 (11 Jun 2013)
  2. GEOS-FP page on the GEOS-Chem wiki
  3. GEOS-5.7.2 page on the GEOS-Chem wiki
  4. MERRA page on the GEOS-Chem wiki
  5. GEOS-5.2.0 page on the GEOS-Chem wiki
  6. Overview of GMAO met data products
  7. Glossary of variables produced by the GEOS-DAS
  8. Evolution of the GEOS-5 system from GEOS-5.2.0/MERRA to GEOS-5.7.2 (aka "Fortuna")

  3. The Collection indicates the GEOS-FP raw data files in which each field may be found.
    • A GEOS-FP raw data file is created for each new date and time.
    • Therefore, the CN data fields listed below will be contained in a single GEOS-FP raw data file.
