This dataset consists of estimated annual and monthly ground-level fine particulate matter (PM2.5) for 1998-2020, by combining Aerosol Optical Depth (AOD) retrievals from the NASA MODIS, MISR, and SeaWIFS instruments with the GEOS-Chem chemical transport model, and subsequently calibrating to global ground-based observations using a Geographically Weighted Regression (GWR), as detailed in the below reference for V5.GL.01. V5.GL.02 follows the methodology of V5.GL.01, but updates the ground-based observations used to calibrate the geophysical PM2.5 estimates for the entire time series, and extends temporal coverage through 2020. Provided grids use WGS84 and are in netCDF format. The grids consists of a 0.01° resolution PM2.5 surface, an associated uncertainty grid, and a coarser 0.1° resolution PM2.5 surface. All units are in µg/m³. More information can be found at https://sites.wustl.edu/acag/datasets/surface-pm2-5/ . Reference: Aaron van Donkelaar, Melanie S.
