    • MERRA-2 avgM_2d_pm25_admin0, 2d, Single-Level, Country-Level Surface PM2.5 Monthly Mean Products V1 (M2_TMAX_PM25) at GES DISC

    Metadata Updated: March 27, 2024

    M2_TMAX_PM25 is a value-added product derived from the MERRA-2 aerosol monthly product M2TMNXAER_5.12.4 (or tavgM_2d_aer_Nx). The surface concentration of fine particulate matter (PM2.5) is calculated as the sum of individual aerosol components (organic carbon, black carbon, sulfate, sea salt, and dust) (Buchard et al., 2017) and is recast from the native MERRA-2 model grid. This data collection includes separate files for country-level (and territories) PM2.5 concentrations with and without population weighting applied.
