List of GEOS-FP met fields

<hr />
<div>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. (The current GMAO FP data are created with [[Version_history_of_GMAO_met_data_products#GEOS-5.11.0|version 5.11.0]] of the NASA GEOS-DAS system). GMAO FP has finer native horizontal resolution (0.25&deg; lat x 0.3125&deg; 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]].<br />
<br />
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. <br />
<br />
'''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".<br />
