PM10 NowCast released

The PM10 NowCast has been deployed, allowing AirNow.gov to report current PM10 conditions. Real-time PM10 alerting capability will be available in EnviroFlash in early 2015. The PM10 NowCast methodology is the same as the PM2.5 Nowcast’s which better captures rapidly changing air quality conditions.

As part of this implementation, existing AirNow maps and animations displaying PM2.5 AQI information will also include PM10 AQI information, and these maps will now be labeled as PM, representing the maximum AQI between both pollutants.

Thank you.
