SummaryThe main objective of this project is the scientific exploitation of selected archived TerraSAR-X data in support of mass balance studies of the great ice sheets of Antarctica and Greenland. Specifically, we seek to improve on our existing continent-wide ice velocity map representing ice velocities during IPY. Spaceborne interferometric SAR data are crucial for measuring ice surface velocity of the great ice sheets on a continental scale. No other sensor provides comparable coverage and measurement accuracy. Building on continent-wide ice velocity product we generated for Antarctica [4,9] and Greenland [3] using other spaceborne SAR missions, we will use selected available (and suitable) TerraSAR-X data to improve upon the existing ice velocity product. Primary focus will be on Antarctica, though we also seek access to data acquired over selected glaciers in Greenland. For Greenland, our primary focus will be on the generation of a continental scale reference map for Greenland for the international Polar Year (IPY). Our geophysical data products derived from spaceborne SAR data are available to the science community [8,9,10]. Access to selected scenes from the TerraSAR-X archive will prove an invaluable source of information in our effort to improve on the existing maps. Updates of our maps will be made available to the science community as they become available. This approach ensures maximum impact of the project and optimal use of the TerraSAR-X archive data.
