IDEA - Infusing satellite Data into Environmental (air quality) Applications
Summer 2003: PrototypeAnalysis, Fusion, and Visualization of
NASA ESE and US EPA data for use in AIRNow
NASA-LaRC/USEPA Air Quality Applications Group
IDEA: NASA-EPA-NOAA partnership to improve air quality assessment, management, and prediction by infusing (NASA) satellite measurements into (EPA, NOAA) analyses for public benefit.
IDEA (Infusing satellite data into environmental air quality applications)
Part of NASA Earth Science Enterprise (ESE) Applications Program strategy to demonstrate practical uses of NASA sponsored observations from remote sensing systems and predictions from scientific research.
AIRNow
• AIRNow is a website to provide the public with easy access to national air quality information. The website offers daily air quality forecasts as well as real-time air quality for over 275 cities across the U.S., and provides links to more detailed State and local air quality websites.
•It is a joint partnership between EPA, State and local air quality agencies. The mission of the AIRNow program is to provide air quality forecasts and real-time air quality information in a visual, easy-to-understand format.

• Real-Time Reporting & Mapping of PM2.5
– Air quality (esp. PM2.5) is a year-round problem & scientific evidence pointing to PM2.5 as a serious health concern
– Over 230 continuous PM2.5 monitors reporting data to AIRNow DMC
– Various mapping approaches being developed, analyzed and implemented
– Target: Maps for the public by October 1, 2003
AIRNow 2003AQI (PM 2.5) Reporting & Mapping
• AQI Forecasting for PM2.5
– Provides year-round coverage– EPA pilot effort focusing on 36 major cities across the
U.S.– Currently developing PM2.5 forecast tools for State and
Local Agencies – MODIS/AIRNow data fusion would be one of many tools
– Target: PM2.5 forecasts for the public for all 36 cities by October 1, 2003
AIRNow 2003AQI (PM 2.5) Forecasting
Source: US EPA, 2003
What: Near-Real-Time Data Fusion of MODIS Direct Broadcast and EPA AIRNow Data (Currently using NOAA Bent Pipe)
When: Summer 2003
Who: NASA LaRC and GSFC
CIMSS/SSEC Univ. Of Wisc.-Madison & NOAA
US EPA OAR/OAQPS
Select group of AQI Forecasters
Objective: Prototype a NRT product for AQI Forecasters
Goal: Improve accuracy of next day PM2.5 AQI forecast during large aerosol events
NASA MODIS - EPA AIRNow Data Fusion Demonstration 2003:
Improving Air Quality Index (PM 2.5) Forecasting
AIRNow Air Quality Index (AQI) PM2.5 forecasting
Data User - AQI Forecasters:
• State & local air management agencies, as well as commercial interest (access to a combined MODIS/TEOM data product will increase forecast skill in next-day regional AQI forecast)
Benefit - AQI Forecasts Users:
• Government and Industry who want take action to reduce source emissions for forecast days with poor air quality
• Commercial media outlets that provide AQI forecast information
• Sensitive populations adversely affected by poor air quality

10 Sept. 2002- A different projection from VGEO shows the results of the forward air parcel trajectories after 53 hrs initialized at 850mb from NOAA/ARL HYSLPIT model. A cluster of the
trajectories appear close to the ground surface in areas of high AOD from MODIS.
