gional atmospheric models from the Texas Commission on Environmental Quality. The collaboration uses satellite data from the Tropospheric Emission Spectrometer on NASA's Aura satellite and the Atmospheric Infrared Sounder on NASA's Aqua satellite to supplement knowledge of ozone and temperature in the lowest portions of Earth's atmosphere above Texas.

Understanding Enhancements in Tropospheric Carbon Monoxide from Biogenic Volatile Organic Compounds Using TES and MOPITT Data
Time: Tues., May 27, 4:15 p.m. EDT, Room 305
Session: A24A-02

Scientists from NASA's Jet Propulsion Laboratory will discuss their study of the sources of chemicals that are the first ingredients of ozone pollution over the southeastern United States. The two main sources are natural sources emitted by trees and vegetation, and human sources by way of autos and industry. Using an atmospheric chemistry model and NASA satellite data of ozone and ozone precursors, the scientists have found that, in certain hot periods of summer, the natural sources of ozone ingredients are responsible for as much as 60 percent of the ozone over some locations in the United States.

Honeybees, Satellites and Climate Change
Time: Wed., May 28, 11 a.m. EDT, Palm Room
Session: U32A-01

NASA researcher Wayne Esaias, a biological oceanographer, will discuss how his current study is using the power of global satellite observations and models to help answer the important but difficult question of how climate change will impact bees and pollination.

Multi-Instrument Study of Effects of Boreal Forest Fires on the Global Upper Troposphere and Lower Stratosphere
Time: Wed., May 28, 1:30 p.m. EDT, Hall A
Session: A33B-02

Due to an increase in the activity and severity of biomass burning observed since the 1950s, more pollution has entered the upper troposphere and lower stratosphere. Data gathered from a variety of instruments shows that increased transport of b
