Project Timeframe: 2006 - 2008

Project Summary:

This project focuses on the development, application, and integration of new NASA earth observation data for use in routine air quality assessment techniques on a regional scale. Under this project we will develop new techniques that will aid EPA Regions and States to assess regional ozone transport for air quality management decision, particularly related to State Implementation Plans.

The Houston-Galveston-Gulf Shore Region in EPA Region VI and the Eastern Great Lakes Region in EPA Region II are two areas impacted by the new eight-hour ozone standard. One of the necessary steps in reducing air pollution is to understand its causes, how it is formed, and how it travels throughout a particular region. One of the primary deficiencies in understanding ozone transport is the paucity of ambient observations to assess transport along with direct comparison of such observations to State Implementation Plan model results. Generally, the only routine measured data available to assess transport originates from the EPA and State and Local low-resolution surface ozone monitoring network. The synoptic scale full tropospheric column data from the Ozone Monitoring Instrument (OMI) aboard the NASA Aura satellite has the potential to provide a major advancement in data sets available for pollutant transport studies.

In this effort, we propose to work with our colleagues at EPA Regions II and VI, along with other key collaborators at NASA and OAQPS, to demonstrate the feasibility of using satellite measurements to enhance existing surface based measurements in the assessment and analysis of the formation and transport of ozone. This project includes the use of new technologies from satellite that, if successful, would accelerate the use of a new measurement technology for use in air quality assessments and forecasting.
