Fine Particulate Matter (PM2.5 v3) (Source...
Ground-level fine particulate matter (PM2.5) total and compositional mass concentrations over North America were estimated 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 reference for V4.NA.02. |V4.NA.03 further modified the V4.NA.02 GWR method with additional developments as part of the MAPLE (Mortality–Air Pollution Associations in Low-Exposure Environments) project, and uses V4.GL.03 PM2.5 estimates as geophysical input. The GWR method of individual components remains unchanged from V4.NA.02, but are provided are percentages to ensure mass closure and recommended to be applied to the V4.NA.03 total PM2.5. |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 2018.
