tavgM_2d_chm_Fx: MERRA Chem 2D IAU Diagnostics, Fluxes and Meteorology, Monthly Mean 1.25 x 1 degree V5.2.0 (MATMFXCHM) at GES DISC

The MATMFXCHM or tavgM_3d_chm_Fx data product is the MERRA Data Assimilation System Chemistry 2-Dimensional chemistry that is time averaged, single-level, at reduced FV resolution. It is a history file that is intended for forcing off-line chemistry/aerosol models with the results of the reanalysis. Like other histories, they are produced from the GCM during the corrector segment of the IAU cycle. All collections from this group are at reduced horizontal resolution. MERRA, or the Modern Era Retrospective-analysis for Research and Application, is a NASA reanalysis for the satellite era (30 years 1979-current) using the Goddard Earth Observing System Data Assimilation System Version 5 (GEOS-5 DAS).

This data product contains fields that do not vary during the reanalysis.

The data are on the GEOS-5 native 288 x 181 grid with 1.25 degree longitude x 1 degree latitude resolution. The files are the monthly means. Data are archived in the HDF-EOS2 (Grid) format, based on HDF4.
