<span style="color:red">'''''NASA/GMAO ceased production of GEOS-5.2.0 data as of June 2013. See GMAO's [https://gmao.gsfc.nasa.gov/GMAO_products/NRT_products.php 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]].'''''</span>

=== List of GEOS-5 Fields used in GEOS-Chem ===
+
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:
  
 +
* [[Overview of GMAO met data products]]
 +
* [[GEOS-5 issues|GEOS-5 issues]]
 +
* [[GEOS-5 met field reprocessing]] '''(NOTE: Completed in 2009)'''

== 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 [http://acmg.seas.harvard.edu/geos/wiki_docs/geos5/GEOS-5.2.0-File_Specification.pdf GEOS-5.2.0 file specification document].

There can be significant differences in the amount of tracer lost to wet scavenging in GEOS-5 as compared to the equivalent run in GEOS-4.  Click [[http://www.as.harvard.edu/ctm/geos/ppt/GEOS_5_precip_comparison.ppt|HERE]] to view a powerpoint that describes some of the differences.

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:

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.
