Abstract:

The Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2), is a global atmospheric reanalysis produced by NASA's Global Modeling and Assimilation Office (GMAO) using the Goddard Earth Observing System (GEOS) model and data assimilation system. The M2TMNXSLV (tavgM_2d_slv_Nx) collection provides monthly mean single-level meteorological diagnostics for the satellite era. This convenience-copy dataset contains M2TMNXSLV data for 1980-present that have been reorganized into variable-specific NetCDF files to facilitate access, analysis, and distribution while preserving the original spatial and temporal characteristics of the source dataset.
