NASA presentations at American Geophysical Union Join...( Researchers will present findings on...)

Researchers will present findings on a variety of NASA-related Earth and heliophysics topics at the 2008 Joint Assembly of the American Geophysical Union. The meeting runs Tues., May 27 through Fri., May 30 at the Greater Fort Lauderdale-Broward County Convention Center, 1950 Eisenhower Blvd., Fort Lauderdale, Fla. Sessions are open to registered news media.

Following are noteworthy NASA presentations, in chronological order:

Evaluation of Lower Tropospheric Ozone Estimates Based on OMI and MLS for Pollution Studies, With a California Example
Time: Tues., May 27, 2:15 p.m. EDT, Room 305
Session: A23A-04

By developing methods for measuring and quantifying estimates of ozone levels in the lower tropospheric layer just above the boundary layer closest to Earth, it may be possible to create climate models to help abate air pollution. Presenters will discuss research efforts focused on ozone affecting the mountainous regions and polluted valleys of California.

What Have We Learned About Global SO2 Pollution With AURA/OMI Data"
Time: Tues., May 27, 2:45 p.m. EDT, Room 305
Session: A23A-06

Presenters will discuss how Auras Ozone Monitoring Instrument (OMI) detects sulfur dioxide emissions from individual power plants and smelters, and how it compares relative strengths and sizes of emissions in different industrial regions of the world. Pollution tracked from East Asia across the Pacific Ocean has implications for air quality in the United States, providing impetus for power plants to meet emission limits and reduce pollution.

Evaluating and Improving the Results of Air Quality Models in Texas Using TES, AIRS and Other Satellite Data
Time: Tues., May 27, 3 p.m. EDT, Room 305
Session: A23A-07

In this session, scientists from NASA's Jet Propulsion Laboratory, Langley Research Center and other organizations will discuss the results of a collaboration that uses NASA satellite data to evaluate re
