Puget Sound Regional Air Quality Map

Air Monitoring Network

To track and forecast air quality, we operate monitoring stations across the Puget Sound region. These stations provide us with data about air pollution levels, weather conditions, and wind information. The map below shows all of the locations, as well as current air quality conditions. The colored dots indicate the latest AQI at that station.

For details about a particular station, hover your mouse over its marker. A pop-up balloon appears with information for that station, including the air pollutant (ozone or particulate matter) with the latest available AQI measurement. Also shown are any other parameters being measured, and whether the monitoring station is maintained by the Clean Air Agency or the Department of Ecology.
