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_lnd_Nx: 2-dimensional, Monthly mean, Time-Averaged, Single-Level, Assimilation, Land Surface Diagnostic

A monthly time-averaged 2-dimensional data collection of land surface parameters is presented in the Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2). It provides global model and data assimilation results that incorporate satellite-based observations to predict monthly land surface parameters such as baseflow flux, runoff, surface soil wetness, root zone soil wetness, water at surface layer, water at root zone layer, and soil temperature.
