SummaryGlaciers and snow cover in polar and sub-polar regions are considered good indicators for climate variations and impacts of climate change. Moreover, their temporal changes have considerable impact also on the adjacent ecosystems as e.g. freshwater influx and sediment plumes in coastal waters. With its remote sensing products the project consortiums will support various glaciological studies and other research activities of internally adopted projects (e.g. ClicOPEN) within the International Polar Year (IPY) 2007 to 2009. The research areas are distributed bi-polar, covering East Antarctica, the Antarctic Peninsula and Patagonia as well as Svalbard, Iceland and Northern Scandinavia. For this purpose TERRA-POLAR will adopt existing methods and develop new tools for a variety of remote sensing applications in glaciology and glacial-hydrology. The activities of the consortium comprise mapping of glacier outlines and their changes, derivation of glacier velocity fields and topographic information with differential SAR interferometry as well as time series analysis for glacier facies mapping over glaciated and periglacial areas with multi-temporal SAR intensity images. Results shall be made available to a larger community and for use of other scientific groups (e.g. glacier outlines via the GLIMS database interface at NSIDC, Boulder; or the Antarctic VelMap database at BAS). TERRA-Polar will make full use of the various modes and products of TerraSAR-X for polar studies. ScanSAR and strip map mode data acquired during winter months will be particularly used for DInSAR analysis, whereas summer imagery will facilitate glacier facies mapping. The high-resolution capabilities will provide the basis mapping of small-scale periglacial snow cover or DInSAR velocity mapping over small glaciers. From the 11 day revisit time improved the products are expected for glacier facies mapping as well as for InSAR since in some areas previous data acquisition was restricted by the operation of a receiving station or the 35 orbits of ERS-1/2 and ENVISAT. Repeat acquisitions might enable the derivation of multiple interferograms and hence enhance the quality assessment of the products. All project partners can rely on long-term experience in polar research and existing bi- and multi-lateral co-operations including intensive field campaigns in Antarctica and joint projects (e.g. ESA GMES, CryoSAT AO). Coordinated ground truth campaigns are anticipated during the IPY. Furthermore, data ordering shall be coordinated and submitted centrally to avoid ambiguities and user conflicts within the consortium (e.g. over the Antarctic Peninsula). All partners can rely on certain core funding of personnel from the university and federal state. Additional funding is already provided by a number of projects and additional proposal-specific funding shall be requested by national funding agencies. A total number of 1455 TerraSAR-X scenes over the entire proposal period is requested for all partners.
