Fine Particulate Matter (PM2.5 v2) (Postal...
We estimate ground-level fine particulate matter (PM2.5) total and compositional mass concentrations over North America by combining Aerosol Optical Depth (AOD) retrievals from the NASA MODIS, MISR, and SeaWIFS instruments with the GEOS-Chem chemical transport model, and subsequently calibrated to regional ground-based observations of both total and compositional mass using Geographically Weighted Regression (GWR) as detailed in the references.Data are provided at 3-year running averages, labelled as the last year included (i.e., average of 1998, 1999 and 2000 is labelled as 2000)These annual 0.01 x 0.01 degree gridded surface datasets were used by CANUE staff to assign values of annual mean concentration of PM2.5, for all postal codes in Canada for each year from 2000 to 2016 (DMTI Spatial, 2015).
