Fine Particulate Matter (PM2.5 v1) (Postal...
Ground-level fine particulate matter (PM2.5) over North America was estimated by combining a 0.01 degree x 0.01 degree resolution optimal estimate-based Aerosol Optical Depth (AOD) retrieval from the NASA MODIS instrument with aerosol vertical profile and scattering properties simulated by the GEOS-Chem chemical transport model. A geographically weighted regression (GWR) that incorporates ground-based observations to adjust for any residual bias in the satellite-derived PM2.5 estimates was then applied. Values prior to 2004 apply the temporal variation of Boys et al., to the GWR-adjusted period. 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 impute values of annual mean concentration of PM2.5, for all postal codes in Canada for each year from 2000 to 2012 (DMTI Spatial, 2015).
