Maps of haze from airport visual data (July-September) show the amount of summertime haze (visibility impairment) during 1970, 1980, and 1990. Haze in the eastern U.S. increased significantly between 1970 and 1980, and decreased slightly between 1980 and 1990.Black Carbon from fossil fuel and biomas burning (23 KB gif image)
