MERRA Monthly Analysis Data Collections


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 monthly data from the MERRA ANALYSIS COLLECTIONS. All data used here are at GEOS-5 native resolution of 2/3 longitude by 1/2 latitude degrees, with 42 vertical pressure levels.

Vertical Profile
Select a vertical profile range. The range selection is disabled unless a qualifying parameter is selected. In order to enable this option (and populate the list with values), select a parameter.
NOTE:  Selected 3D parameters must have the same 3rd dimension (e.g., pressure, altitude, wavelength, etc.) units in order to enable the vertical level menu.
