NASA Ames Scientists Featured at American Geophysical Union Meeting
MOFFETT FIELD, Calif. – Scientists from NASA’s Ames Research Center will discuss 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.
Following are noteworthy NASA Ames 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, Presented by Robert B. Chatfield
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. 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, Presented by Jimena Lopez
Due to an increase in the activity and severity of biomass burning observed since the 1950’s, more pollution has entered the upper troposphere and lower stratosphere. Data gathered from a variety of instruments shows that increased transport of biomass pollution due to climate change can be expected. Presenters will discuss how recent observations illustrate that highly polluted smoke-laden air from these fires can be injected into the upper troposphere and even the stratosphere. Convective History of Thin Cirrus Clouds Observed During TC4 Time:
Fri., May 30, 2:45 p.m. EDT, Room 305 Session:
A53B-02, Presented by Leonhard Pfister
The presenter examines a number of subvisible cirrus cloud cases, folding together trajectory analyses, temperature soundings, and A-Train satellite cloud and water vapor data to fully understand the history of the air in which the cloud is observed. These thin clouds were observed on a number of occasions by lidar instrumentation on board two aircraft during the recent Tropical Clouds, Chemistry, and Climate Coupling (TC4) experiment.
