Scatter plots of PM2.5 concentrations based on measurements from regulatory monitoring networks (Inhalable Particulate Network (IPN) or Federal Reference Method (FRM)) and predictions at census tract centroids and national grid coordinates estimated by the historical prediction model across 51 Metropolitan Statistical Areas by 1980s (1979–1983), 2000s (1999–2000), and 1980s-2000s (1979–1983 minus 1999–2000) (green and red lines for the identity and best-fitted lines, respectively; the 1st to 3rd row displaying measured vs. census tract-based modeled PM2.5, measured vs. national grid-based modeled PM2.5, and modeled census tract-based vs. modeled national grid-based PM2.5, respectively)
