Fine Particulate Matter (PM2.5 v4) (Source...
Estimates of 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.
