Her talk Sept. 14 is titled “Using Satellite Data to Study Interconnections of Earth Systems” and will be presented at 3 p.m. in Room 407 in the Chemistry, Astronomy and Physics Building on Rivers Street in Boone. The public is invited to attend.

The talk is part of the university’s Chemistry Seminar Series and sponsored by the Department of Geography and Planning’s NASA-funded CAN-DOO project, Appalachian’s Research Institute for Environment, Energy, and Economics, and the College of Arts and Sciences. CAN-DOO stands for Climate Action Network Through Direct Observations and Outreach.

Hall’s talk at Grandfather Mountain on Sept. 15 is titled “Observing Our Changing Planet from Space” and will be part of the 42nd annual Girl Scout Day. The talk begins at 1 p.m. in the Nature Museum Auditorium. All Girl Scouts and troop leaders will be admitted free with proof of membership. The lecture is also open to others visiting the mountain that day.

Hall is a senior research scientist in the Cryospheric Sciences Branch at NASA/Goddard Space Flight Center, Greenbelt, Md., where she is involved in research related to the remote sensing of snow and ice including studies of snow cover, glacier ice, lake ice and sea ice.

In July, Hall confirmed the unprecedented ice melt that occurred on Greenland using the Moderate-resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites. MODIS data showed unusually high temperatures and that melt was extensive over the ice sheet surface.

Hall also has led and been involved in field experiments in the northern U.S., Canada and the Arctic.

Her MODIS-related snow and Greenland research may be seen at the MODIS Snow and Ice website at http://modis-snow-ice.gsfc.nasa.gov.

Hall has been an adjunct faculty member at the University of North Carolina at Wilmington in the Department of Geography and Geology (2009–2010), an affiliated professor at George Mason University in the Earth Science and GeoInformation Systems Department (2005–2006), and a distinguished visiting scientist at the University of Delaware’s Department of Geography (2002–2003).

She is an editorial board member for the journal Remote Sensing of Environment, and a scientific associate editor for the journal The Cryosphere.
