Summary
Abstract: The MAI6NVANA or inst6_3d_ana_Nv data product is the MERRA Data Assimilation System 3-Dimensional instantaneous, on model levels, at native 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 2-dimensional and 3-dimensional fields that do not vary during the reanalysis.

The data are on the GEOS-5 native 540 x 361 grid with 2/3° longitude x 1/2° latitude resolution. File sizes are about 1347 Mbytes per day with the following times compacted into a daily file: 00, 06, 12, 18 GMT. Data are archived in the HDF-EOS (Grid) format, based on HDF4.
