Description:

NOTE: The MERRA reanalysis dataset production was completed on February 29, 2016. MERRA-2, which incorporates various advances is currently in production.
The Modern-Era Retrospective analysis for Research and Applications (MERRA) dataset was released in 2009. It is based on a version of the GEOS-5 atmospheric data assimilation system that was frozen in 2008. MERRA data span the period 1979 through February 2016 and were produced on a 0.5 degree by 0.66 degree grid with 72 layers. MERRA was used to drive stand-alone reanalyses of the land surface (MERRA-Land).
