But MERRA-2 uses the identical vertical grid as the [[GEOS-5#GEOS-5|GEOS-5]], [[MERRA]], and the "[[GEOS-FP]]" data products used by GEOS-Chem. | |

MERRA-2 is a new NASA/GMAO reanalysis product. It has a horizontal resolution of 0.5° lat x 0.625° lon x 72 vertical levels. The horizontal resolution is 2x coarser than the GMAO "forward processing" product (which we refer to as GEOS-FP). But MERRA-2 uses the identical vertical grid as the GEOS-5, MERRA, and the "GEOS-FP" data products used by GEOS-Chem.
NOTE: GEOS-Chem only uses a subset of the entire MERRA-2 data archive. On this page we list the MERRA-2 met fields that we archive for use with GEOS-Chem.
