Campus Air Quality Map

Air quality may change quickly depending on wildfire intensity and weather conditions. This map is updated hourly and reports data as “Current AQI” using the EPA’s PM2.5 NowCast AQI algorithm. Refer to the UC AQI Decision-Making Matrix and the University of Health Services Wildfire Smoke webpage for recommended actions. For decision-making, the sensor at Stanley Hall is considered representative of the central campus. 

For additional technical information regarding this map, PM2.5 reference monitors, and sensor data please visit the Wildfire Smoke Monitoring Information webpageIf your site is not represented by the Campus Air Quality Map, please refer to these resources for information about local air quality conditions and take actions consistent with our University of California AQI‐Based Decision‐Making Matrix for Wildfire Smoke Events or consult EH&S for assistance.
