Scatter plots of PM2.5 (μg/m3) and life expectancy for 1980–2000 across 211 U.S. counties using Metropolitan Statistical Area (MSA) average PM2.5 concentrations based on measurements from regulatory monitoring networks (Inhalable Particulate Network (IPN) or Federal Reference Method (FRM)) vs. county average PM2.5 concentrations based on predictions at census tract centroids (CT) and national grid coordinates (NG) estimated by the historical prediction model by 1990s, 2000s, and 1980s-2000s
