Abstract The changes and causes of reduced visibility in the Eastern U.S. during the past three decades were examined. Contour maps of local midday extinction coefficients (inversely related to visibility) are presented. Daily mean extinction coefficient maps illustrate the formation and movement of air masses with reduced visibility; they are supplemented by tables and stripcharts of regional meteorological parameters. Plots of quarterly average extinction coefficients illustrate the long term seasonal and spatial trends of visibility.
