Using instruments onboard NOAA’s geostationary and polar-orbiting weather satellites, scientists are working to more accurately forecast the effects of wildfire smoke on AirQuality. Learn more:
This is the threshold for exposure that, if exceeded during a 24-hour period, the Environmental Protection Agency considers unsafe, particularly for sensitive individuals. Local environmental agencies in more than 360 U.S.
Monthly mean PM2.5 for August 2019 predicted from NWS experimental CMAQ model simulations. EPA AirNow observations from ground monitors are shown as closed filled circles with the same color scale as model predictions.

In addition to the CMAQ model, the RAVE data will be ingested into the Rapid-Refresh Forecasting System for high-resolution smoke forecasting over North and Central Americas. The experimental RRFS model is currently being developed for weather forecasting at NOAA’s . The RAVE data will be used to estimate the wildland fire emissions and heat fluxes in the RRFS-Smoke model. The RRFS-Smoke model will be initialized every hour, thus taking advantage of the high-frequency RAVE fire data.
