Short Biography

Dr. Hall performs research on the remote sensing of snow and ice. She is principal investigator for the Moderate Resolution Imaging Spectroradiometer (MODIS) Snow and Sea Ice Mapping Project that develops and maintains snow and ice algorithms for products used by researchers worldwide. She is also a principal investigator on a snow product validation project for the Visible Infrared Imager Radiometer Suite —a scanning radiometer onboard NASA's newest Earth-observing satellite, Suomi NPP— and on a Greenland ice surface temperature project. She's co-investigator on other cryosphere-related projects.

She 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 Department of Geography (2002 – 2003). 

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

She is co-leader of a snow cover focus group for Committee on Earth Observation Satellites Land Product Validation, and a member of the editorial board of NASA's Earth Observatory website.

Dr. Hall's MODIS-related snow and Greenland research may be seen on the MODIS Snow and Ice website.
