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

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.
