Estimated global annual surface fine particulate matter (PM2.5) concentrations for 1998-2018. Aerosol optical depth (AOD) from the NASA MODIS C6.1, MISR v23, MAIAC C6, and SeaWiFS satellite products are combined and related to surface PM2.5 concentrations using geophysical relationships between surface (PM2.5) and AOD simulated by the GEOS-Chem chemical transport model. These estimates are subsequently calibrated to global ground-based observations of (PM2.5) from the World Health Organization using Geographically Weighted Regression (GWR). These estimates identify significant regional trends, as detailed in the reference below. These data are specifically associated with the publication Hammer, M. S.; van Donkelaar, A.; Li, C.; Lyapustin, A.; Sayer, A. M.; Hsu, N. C.; Levy, R. C.; Garay, M. J.; Kalashnikova, O. V.; Kahn, R. A.; Brauer, M.; Apte, J. S.; Henze, D.
