This is a map of ozone air pollution in the eastern United States during the present smog episode. The orange areas had air that was unhealthy for sensitive individuals on Wednesday, May 2, 2001. The ozone was expected to continue on Thursday and Friday before clouds from a cold front on Friday night bring an end to this ozone episode.

The map shows that air pollution problems can be found outside of major urban centers. The map is from the AIRNow website, which provides the public with easy access to national air quality information. The website offers daily air quality forecasts as well as real-time air quality for over 100 cities across the U.S. The site provides links to more detailed State and local air quality websites and gives suggestions on what people can do to help improve the air quality where they live. States provide these data to the website and to newspapers, radio and television stations in their areas. The site also includes animations of each day's ozone that show how ozone is formed and transported.
