US National Aeronautics and Space Administration (NASA) Global Modeling and Assimilation Office (GMAO) Modern-Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) tavgM_2d_slv_Nx: 2-dimensional Monthly mean, Time-Averaged, Single-Level, Assimilation, Single-Level Diagnostics (M2TMNXSLV), Version 5.12.4

A monthly time-averaged 2-dimensional data collection of surface-level, meteorological parameters are available in the Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2). It contains global model and data assimilation results that incorporate satellite-based observations to predict monthly, surface-level, atmospheric meteorological parameters such as air temperature, wind components, sea level pressure, surface pressure, and total precipitable water vapor.
