Abstract
Geographical, seasonal and long term variations in turbidity for the period 1967-1976 from the EPA/NOAA turbidity network are described. A model relating atmospheric turbidity to relative urbanization is also presented. The 1967-1976 data show that increases in annual average nonurban turbidity since the first five years of turbidity monitoring (1961-1966) are primarily found over the southeastern United States with increases of about 30%. During 1967-1976 annual average turbidity increases primarily at stations in the Southeast. This increase is due mostly to increasing summer turbidity. The model which is developed involves the separation of annual average urban turbidity into background and local effects terms where local effects are related to the local urban area population.
