Frequent Questions

Why don't maps show up for my area?

State and local air pollution agencies operate and maintain air quality monitors across the country. These agencies send the data to the AirNow program so that we can make the maps. However, not all states choose to submit data to AirNow.

Sometimes you can get additional information for your area from a state or local agency's own Web site, many of which can be found at the AIRNow Partners link.
