PM2.5 Sensors Map (PurpleAir) website (use LRAPA conversion)
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” or "LRAPA" to apply a correction factor.] Also check out the
the Sensor Data Layer on the newly updated
EPA AirNow Fire & Smoke Map which includes PurpleAir sensors (New in 2020!).

[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.
