About This Data

Rankings are based on real-time Air Quality Index (AQI) data from EPA monitoring stations via the AirNow network. The AQI measures five major pollutants: ground-level ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide. Lower AQI values indicate cleaner air. Data is updated hourly as new measurements become available.
