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:

"Realtime" AQ Maps & AQI:
  • EPA AirNow (Realtime AQI) - Updated site
  • . [Select "Monitors - PM (PM2.5 & PM10)" & "Contours - PM2.5", then zoom in ("Ozone & PM" will show No Data/ND, as Eureka/Humboldt has a PM10 monitor)]. The "current" AQI indicated is actually a 24-hour NowCast average.

  • EPA AirNow (Realtime AQI) - Previous site
  • 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). The "current AQI" indicated is actually a 24-hour NowCast average.

  • PurpleAir Sensors - Community-based PM (smoke) Sensors Unofficial citizen-science air quality data from low-cost sensors. Sensors should not be used for official air quality readings. Although various AQIs are shown, it is not relying upon District monitors (see EPA AirNow above) - note that the "current" AQI on AirNow is actually a 24-hour average NowCast AQI. [Switch the Map Data Layer dialogue box in the lower left hand corner from “None” to “AQ and U” to apply a correction factor.]Check out the EPA Air Sensor Toolbox.
