AirNow Fire and Smoke Map

Associated Agencies

U.S. Environmental Protection Agency (EPA), U.S. Forest Service, University of Washington

The AirNow Fire and Smoke Map is an interactive map displaying information on ground-level air quality monitors recording fine particulates (PM2.5) from smoke and other sources, as well as information on fires, smoke plume locations, and special statements about smoke issued by various sources.

AirNow reports air quality using the official U.S. Air Quality Index (AQI), a color-coded index designed to communicate whether air quality is healthy or unhealthy.

This map is a collaborative effort between the U.S. Forest Service led Interagency Wildland Fire Air Quality Response Program (IWFAQRP) and the U.S. Environmental Protection Agency. Development work was done through an agreement with the University of Washington’s School of Environmental and Forest Sciences.
