AirNow (Fires:Current Conditions)(the "current" AQI indicated is actually a 24-hour NowCast average)

Community-based Particulate (smoke) Sensors - PurpleAir Unofficial citizen-science air quality data from low-cost sensors. Although sensors provide shorter-term air quality data, they should not be used for official air quality readings as they have reliability and accuracy limitations. The AQI indicated is not based upon District regulatory 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.
