How to check your AQI (Air Quality Index)

AirNow is a partnership of the U.S. Environmental Protection Agency, National Oceanic and Atmospheric Administration (NOAA), National Park Service, NASA, Centers for Disease Control, and tribal, state, and local air quality agencies. They provide easy access to your local Air Quality Index, a measurement that runs from 0 to 500. The higher the number, the more air pollution is present (and the greater the health risk).
