− | + | The GMAO "forward processing" (aka GMAO FP or GEOS5-FP) met field product is the latest update of the GMAO GEOS-5 met data product. GEOS FP 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]], [[MERRA|the MERRA reanalysis]], and [[GMAO GEOS-4|GEOS-4]]. See GMAO's [https://gmao.gsfc.nasa.gov/GMAO_products/NRT_products.php GEOS Near-Real Time Data Products] page for more details. | |
− | GEOS- | + | NOTE: GEOS-Chem only uses a subset of the entire [https://gmao.gsfc.nasa.gov/products/documents/GEOS_5_FP_File_Specification_ON4v1_0.pdf GMAO FP data archive]. On this page we list the [[GEOS-FP|GMAO FP]] met fields that archive for use with GEOS-Chem. |
− | + | '''GEOS-FP is the name of our GEOS-Chem met field archive of the GMAO FP product.''' In the discussion below, we will use the terminology "GEOS-FP" in place of "GMAO FP" or "GEOS-5 FP". | |

The GMAO "forward processing" (aka GMAO FP or GEOS5-FP) met field product is the latest update of the GMAO GEOS-5 met data product. GEOS FP 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. See GMAO's GEOS Near-Real Time Data Products page for more details.
NOTE: GEOS-Chem only uses a subset of the entire GMAO FP data archive. On this page we list the GMAO FP met fields that archive for use with GEOS-Chem.
GEOS-FP is the name of our GEOS-Chem met field archive of the GMAO FP product. In the discussion below, we will use the terminology "GEOS-FP" in place of "GMAO FP" or "GEOS-5 FP".
For more information, please see:
- GEOS5-FP file specification document, Version 1.0 (11 Jun 2013)
- GEOS-FP page on the GEOS-Chem wiki
- Overview of GMAO met data products
- Glossary of variables produced by the GEOS-DAS
- Evolution of the GEOS-5 system from GEOS-5.2.0/MERRA to GEOS-5.7.2 (aka "Fortuna")
