Abstract
The U.S. haze patterns and trends since 1960 are presented in 16 haze maps that represent four time periods and four seasons. The selected time periods are 5 year averages centered at 1960, 1970, 1980, and 1990. The quarters are calendrical. The discussion will encompass the overall national pattern and trends.
