    • MERRA-2 tavgC_3d_ltm_Np: 3d, Long Term Mean 3-Dimensional Meteorological Fields V1 (M2TCNPLTM) at GES DISC

    Metadata Updated: December 7, 2023

    The Modern Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) contains a wealth of information that can be used for weather and climate studies. By combining the assimilation of observations with a frozen version of the Goddard Earth Observing System (GEOS), a global analysis is produced at an hourly temporal resolution spanning from January 1980 through present (Gelaro et al., 2017). It can be difficult to parse through a multidecadal dataset such as MERRA-2 to evaluate the interannual variability of weather that occurs on a daily timescale, let alone determine the occurrence of an extreme weather event. This data collection is a climatological long term mean and standard deviation representing the interannual variability on a monthly timescale.
