Dorothy Hall is an Adjunct Professor in the Department of Geography, and a Senior Scientist Emeritus at NASA / Goddard Space Flight Center in Greenbelt, Maryland where she retired as Associate Chief of the Cryospheric Sciences Laboratory. She received her Ph.D. in Geography from the University of Maryland. Currently she leads the NASA Snow Office located at Goddard Space Flight Center in Greenbelt, Maryland, and is on the organizing committee of NASA’s multi-year SnowEx aircraft mission (2016-2021) for testing sensors to measure snow-water equivalent remotely. She has focused her research on the remote sensing of sea ice, lake and river ice, small glaciers, snow cover and the Greenland Ice Sheet. In recent years she has been focusing on snow-cover mapping and measuring the surface temperature of the Greenland Ice Sheet using Moderate-Resolution Imaging Spectroradiometer (MODIS) satellite data. While at NASA she led a team in the development and production of algorithms to map snow cover and sea ice using MODIS data. She also led the development of daily ice-surface temperature maps of the Greenland Ice Sheet. Dr. Hall has led or participated in field and aircraft missions in the continental U.S., Alaska, Canada, Greenland and Svalbard, and has authored 140 journal articles, numerous other reports and papers, 18 book chapters, and one book — Remote Sensing of Ice and Snow, by D.K. Hall and J. Martinec (1985). Nearly all of her publications deal with various aspects of cryosphere research. She has also been on master’s and Ph.D. committees for numerous students at various universities in the U.S. and has mentored many others.
