Abstract

ERS-ENVISAT cross-interferometry is a unique tool for a number of applications since it combines a short repeat-pass interval (28 minutes) with a long perpendicular baseline (2 km). In the present work a methodology to use the cross-interferogram phase to map the ice thickness of frozen tundra lakes and northern rivers. After presenting the methodology used examples over sites in northern Canada and Siberia are shown. For one site the results could be compared to in-situ measurements and showed good correspondence.
