Improved monitoring of polar land ice dynamics by means of SAR interferometry: ICEDANCE

The paper outlines a proposal which is entitled "ICEDANCE" for a two SAR satellite interferometry mission to investigate the dynamics of the cryosphere. The mission shall be divided in two phases: a motion mode phase, where the two satellites are separated by several hours or even days and a DEM mode phase, where the satellites fly in close formation, at a distance of tenths to hundreds of meters. ICEDANCE adresses key scientific aspects and contributes to major international programs related to processes of the dynamic earth and of climate change. It will lead to a better understanding of sea level change, mass balance of glaciers and ice sheets, freshwater influx to oceans, and thereby enhance our ability to generate more reliable scenarios of possible future change
