  • Sensor Data on the AirNow Fire and Smoke Map

    EPA and the U.S. Forest Service (USFS) are conducting the AirNow Sensor Data Pilot to show data from air sensors on the Fire and Smoke Map, located on the AirNow.gov website.

Air sensor monitors that are lower in cost, portable and generally easier to operate than regulatory-grade monitors are widely used in the United States to understand air quality conditions. This website provides the latest science on the performance, operation and use of air sensor monitoring systems for technology developers, air quality managers, citizen scientists and the public. The EPA is involved in the advancement of air sensor technology, including performance evaluations of sensor devices and best practices for effectively using sensors. The information can help the public learn more about air quality in their communities.
