Current Air Quality Maps & AQI
Current AQI Forecasts (PSA's, Advisories, Alerts):
- Wildfire Smoke AQI Forecasts NCUAQMD issued AQI Forecasts (PSA's, Advisories, Alerts) during wildfires for the public, press, and schools.
Additional wildfire smoke resources:
- AirNow (Fires:Current Conditions)
- USFS AirFire Monitoring 4.1 (Realtime/Nowcast AQI) Fixed (BAMs) and portable (EBAM) monitor data.
- NOAA High Resolution Rapid Refresh (HRRR) [Choose "Visualization on Interactive Map" and then view for "Near Surface Smoke"].
- Community-based Particulate (smoke) Sensors - PurpleAir Unofficial air quality data - PurpleAir sensors are being used on a trial basis and cannot be used for official air quality readings. Although AQI is shown, it is not relying upon District monitors (see EPA AirNow above). [Switch the Map Data Layer dialogue box in the lower left hand corner from “None” to “AQ and U” to apply a correction factor.]
"Realtime" AQ Maps & AQI:
- "UPDATED" EPA AirNow (Realtime AQI) [Select "Monitors - PM (PM2.5 & PM10)" & "Contours - PM2.5", then zoom in ("Ozone & PM" will show No Data, ND).]
- "Previous" EPA AirNow (Realtime AQI) Previous EPA AirNow AQ site - only shows contours. Note that AQI contours are made by an algorithm - if a District monitor in the area is down or not reporting then the map shown could be erroneious (as the algorithm will use outside monitor data).
- Community-based Particulate (smoke) Sensors - PurpleAir Unofficial air quality data - PurpleAir sensors are being used on a trial basis and cannot be used for official air quality readings. Although AQI is shown, it is not relying upon District monitors (see EPA AirNow above). [Switch the Map Data Layer dialogue box in the lower left hand corner from “None” to “AQ and U” to apply a correction factor.]
