NASA presentations at American Geophysical Union Joint Assembly

iomass 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.

The Influence of European Pollution on Ozone in the Near East and Northern Africa
Time: Wed., May 28, 1:45 p.m. EDT, Room 304
Session: A33E-02

Bryan Duncan of NASA and the University of Maryland Baltimore County, will discuss a modeling study of the long-range transport of pollution from Europe, showing that European emissions regularly elevate surface ozone significantly in summer in northern Africa and the Near East, impacting air quality in those regions.

Can Dust from Patagonia Reach Antarctica" A Case Study of Long-Range Transport over the Southern Ocean
Time: Wed., May 28, 3:15 p.m. EDT, Room 304
Session: A33E-08

NASAs Santiago Gasso will discuss an initial assessment based on first-ever satellite images indicating that large dust plumes mixed with clouds originated in Patagonia and extended along the southwest South Atlantic during 2005. The results are unique according to Gasso as the past has been marked with a lack of observational evidence that corroborates both dust activity in Patagonia and the long range transport to Antarctica.

In-Situ F2 Region Electron Density and Temperature Measurements from the International Space Station
Time: Thurs, May 29, 8:30AM EDT, Hall A
Session: SA41A-03

Instruments onboard the International Space Station provide unique measurements about the station's electromagnetic charge and the immediate space weather environment. Researchers will discuss how they will use these instruments, now validated, for scientific space weather studies and to ensure the safety of astronauts during space walks.

Explaining Warm Coronal Loops
Time: Thurs., May 29, 9:45 a.m. EDT, 2008, Room 316
Session: SP41C-06
