About These Rankings

Rankings are based on real-time Air Quality Index (AQI) data from EPA monitoring stations via the AirNow network. The AQI is calculated from measurements of 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. Rankings update as new data becomes available throughout the day.
