    • MERRA-2 tavgM_2d_lfo_Nx: 2d,Monthly mean,Time-Averaged,Single-Level,Assimilation,Land Surface Forcings 0.625 x 0.5 degree V5.12.4 (M2TMNXLFO) at GES DISC

    Metadata Updated: October 23, 2025

    M2TMNXLFO (or tavgM_2d_lfo_Nx) is a time-averaged 2-dimensional monthly mean data collection in Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2). This collection consists of land surface forcing parameters, such as bias corrected precipitation, shortwave and longwave radiation at surface. The collection also includes variance of certain parameters. MERRA-2 is the latest version of global atmospheric reanalysis for the satellite era produced by NASA Global Modeling and Assimilation Office (GMAO) using the Goddard Earth Observing System Model (GEOS) version 5.12.4. The dataset covers the period of 1980-present with the latency of ~3 weeks after the end of a month.
