inst1_2d_int_Nx: MERRA 2D IAU Diagnostic, Vertical Integrals and Budget Terms, Time Average 1-hourly 0.667 x 0.5 degree V5.2.0 (MAI1NXINT) at GES DISC

The MAI1NXINT or inst1_2d_int_Nx data product is the MERRA Data Assimilation System 2-Dimensional vertical integral that is Instantaneous single-level at the native resolution. It is a history file that is produced from the GCM during the corrector segment of the IAU cycle. All collections from this group are at reduced horizontal 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 fields that do not vary during the reanalysis.

The data are on the GEOS-5 native 540 x 361 grid with 0.667 degree longitude x 0.5 degree latitude resolution. Data are archived in the HDF-EOS2 (Grid) format, based on HDF4.
