SummaryThe main objective of this project is the scientific exploitation of TerraSAR-X data in support of producing geophysical information of the great ice sheets of Antarctica and Greenland. Specifically, we seek to expand on our existing continent-wide ice velocity reference maps for IPY and provide follow-on velocity and grounding line products. These maps are key input for mass balance studies for the ice sheets as well as for ice sheet modelers who estimate the contribution of the Antarctic ice sheet to sea level rise (SLR). The combined use of many different SAR data sources will result in continent-wide data products (improvements respectively) that will greatly improve our understanding of the great ice sheets and their response to global change. Data from TerraSAR-X will prove an invaluable source of information in our effort. TerraSAR-X will be used to acquire high-resolution Stripmap data in key areas in coastal regions of the ice sheet. We have identified Totten Glacier and Moscow University Glacier as primary AOI in Antarctica but propose to identify other areas in Antarctica and Greenland throughout the project depending on the data budget and in consultation with DLR. The geophysical data products derived from spaceborne SAR data will be made available to the science community through NSIDC free of charge. This approach ensures maximum impact of the project and optimal use of the TerraSAR-X data.
