AB: Continental Ice Sheets such as Antarctica and Greenland play a major role in the stability of the Earth's climate. These large ice masses are sensitive to changes in global temperatures and have an impact of planetary radiation balance, climate, and sea level. Investigating spatio-temporal variations of ice shelf surface energy balance at moderate scales ranging between tens of meters to kilometers would greatly enhance detection and long-term monitoring of the onset, duration, and magnitude of vigorous melt dynamics. Currently, automatic weather station (AWS) units are deployed in remote regions throughout Greenland and Antarctica. AWS units measure air temperature, wind speed and direction, air pressure, relative humidity. We have developed a prototype system consisting of a dynamic mast apparatus, meteorlogical instrument package, and track platform. A distributed network of these units that are relatively cheap, wireless capable, could provided am adaptive moderate scale monitoring system designed to augment the existing AWS network. Such a network would greatly improve our capacity as ice sheet scientists to assess the stability of these vital structures.
