MERRA Hourly History Data Collections (2D)


Home

The MERRA is a NASA reanalysis for the satellite era using a major new version (V5) of the Goddard Earth Observing System (GEOS) Data Assimilation System (DAS). The MERRA focuses on historical analyses of the hydrological cycle on a broad range of weather and climate time scales.

This MERRA Instance of Giovanni focuses on visualizing and analyzing the MERRA hourly 2D data from the MERRA HISTORY COLLECTIONS. All data used here are at GEOS-5 native resolution of 2/3 longitude by 1/2 latitude degrees.

Currently this instance contains only part of the MERRA hourly 2D variables. The rest of them will be added in the future releases.
