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 for the years 1973-1977. 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. |
