The MERRA2 was introduced to replace the original MERRA dataset because of the advances made in the assimilation system that enable assimilation of modern spectral radiance and microwave observations, along with GPS Radio Occultation datasets. It also uses NASA's ozone profile observations that began in late 2004. Additional advances in both the GEOS model and the GSI assimilation system are included in MERRA2. onGoing datahelp@ucar.edu pointOfContact irregular dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral MERRA-2 > The second Modern-Era Retrospective analysis for Research and Applications U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 2.5 1.25 0.625 eng utf-8 climatologyMeteorologyAtmosphere -180.0 180.0 -90.0 90.0 1980-01-01T0000+00 2026-01-31T2100+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 80089871.591 https://gdex.ucar.edu/datasets/d313003/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d313003/dataaccess/ https Data Access Related Link download none asNeeded
