Infusing satellite Data into Environmental Applications (IDEA): R. Bradley Pierce NOAA/NESDIS/STAR 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)
NASA MODIS - NOAA GOES- EPA AIRNowData Fusion Improving EPA Air Quality Index (PM 2.5) Forecasting 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 http://www.star.nesdis.noaa.gov/smcd/spb/aq/index.php
Operational Use of Satellite Data for Air Quality Index Values Category Cautionary Statements PM2.5 (ug/m3) PM10 (ug/m3) 0-50 Good None 0-15.4 0-54 51-100 Moderate Unusually sensitive people should consider reducing prolonged or heavy exertion 15.5-40.4 55-154 101-150 Unhealthy for Sensitive Groups Sensitive groups should reduce prolonged or heavy exertion 40.5-65.4 155-254 151-200 Unhealthy Sensitive groups should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion 65.5-150.4 255-354 201-300 Very Unhealthy Sensitive groups should avoid all physical activity outdoors; everyone else should avoid prolonged or heavy exertion 150.5-250.4 355-424 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.
