R. Bradley Pierce
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.
IDEAis 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)
Objective:Near-real-time product for State and Local Air Quality Forecasters
Goal: Improve accuracy of next day PM2.5 AQI forecast during large aerosol events
Operational Use of Satellite Data for Air Quality
Unusually sensitive people should consider reducing prolonged or heavy exertion
Unhealthy for Sensitive Groups
Sensitive groups should reduce prolonged or heavy exertion
Sensitive groups should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion
Sensitive groups should avoid all physical activity outdoors; everyone else should avoid prolonged or heavy exertion
Can satellite data be used in near-real-time to provide synoptic-scale features for air quality forecast?
- PM2.5 levels reached Moderateto Unhealthy for Sensitive Groups on Sept. 8th - 12th, 2003 in the Mid-west.
