| Summary: | The monitoring of ocean currents is an important aspect of assessing climate changes. Space borne SAR along-track interferometry (ATI) has the potential to significantly contribute to this field. It can provide largearea, world-wide surface current measurements. The problem of mapping comparatively low velocities can be solved by formations of SAR satellites that allow for sufficiently sensitive ATI measurements. We report on a case study in the Baltic Sea, where we investigate surface currents with the TanDEM-X satellite formation. First ATI data have been analyzed and the results indicate the suitability of the method. The paper gives an overview on the study that includes comprehensive TanDEM-X ATI data acquisition and processing as well as comparison to reference data and to a coupled sea-ice model. |
