Research Group Rott

Research Topic

Satellite observations of ice sheets and glaciers

Research Interest

Development of methods for satellite observations on mass balance and dynamics of ice sheets and glaciers, including synergy with in situ measurements and studies of ice/climate interactions. Participated in several field campaigns in Antarctica (Dronning Maud Land, Antarctic Peninsula, Ellsworth Mountains), Greenland, Patagonia. Current projects focus on volume change, mass balance and dynamic response of glaciers on the Antarctic Peninsula, Patagonia, Iceland, global snow cover monitoring, and on the operational generation of ice velocity maps for Greenland and Antarctica, including time series on velocity and calving fluxes of outlet glaciers (available at http://cryoportal.enveo.at).
