Thursday, September 18th - Mobile Smoke Monitoring Data is available from AirNow**

Real-time emergency smoke monitoring data is available on a new AirNow website specifically for wildfire smoke.  **The site is still under development, not all deployed monitors' data shows. Work continues to be done to upgrade it. (See the smoke summaries posted on this blog for results from all the relevant sites).

Keep in mind that the AirNow method for calculating AQI colors is based on unvalidated hourly data.  The reported colors are based on a custom mathematical algorithm (called NowCast) that relates those hourly values to the 24 hour AQI scale. This algorithm can produce different results (AQI colors) than those reported in the more detailed smoke impact summaries in the smoke reports, which simply report 3 and 24 hr averages against AQI colors based on breakpoints set forth in the Wildfire Smoke, A Guide for Public Health Officials, a document published by California Air Resources Board in 2012.
