PM2.5 forecasting tool hosted at NOAA NESDIS using NASA MODIS (Moderate Resolution Imaging Spectroradiometer), GOES derived aerosol optical depth (AOD) and US EPA AIRNow PM2.4 network.
IDEA is a NASA- EPA-NOAA partnership to improve air quality assessment, management, and prediction by infusing (NASA) satellite measurements into (EPA, NOAA) analyses for public benefit. The IDEA web-based analysis, forecast, and visualization system is hosted at the NOAA Center of Satellite Applications and Research (STAR)
Can satellite data be used in near-real-time to provide synoptic-scale features for air quality forecast?- PM2.5 levels reached Moderate to Unhealthy for Sensitive Groups on Sept. 8th - 12th, 2003 in the Mid-west.
Operational Use of Satellite Data for Air Quality
Sensitive groups should avoid all physical activity outdoors; everyone else should avoid prolonged or heavy exertion
Sensitive groups should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion
Sensitive groups should reduce prolonged or heavy exertion
Unusually sensitive people should consider reducing prolonged or heavy exertion
None

There are six sections to the site.
For each section you can selectTerra, Aqua or GASP data.
GASP is the GOES aerosol productGASP is a geosynchronous satellite.Although it provides high temporalsampling the spectral range,spatial resolution andcalibration accuracy are not asgood as what MODIS provides.
The Regional Plotssection allows you to zoom in on AOD in anyone of the U.S. EPARegions.
Prior to selecting the zoomregion you can obtainimages, animations and kmlfiles for the entire U.S.
The Regional Plotssection allows you to zoom in on AOD
The 48 Hour Trajectory Panel
Animated trajectories of aerosol with winds Verification plot of AOD 48 hours after start
Three day composite historyof AOD.
Also available areWinds, Fire and PM 2.5 ground measurements.
PM Estimation from AOD
This is a composite of estimate of ground level AOD using MODISdata only

Time Series Plots
Selecting this section brings up a map of theU.S.
