Remote Sensing

Surface flow measurements : We use airborne and satellite measurements to study the evolution of glaciers (radar interferometry, lidar, photogrammetry). In particular, we are developing innovative image correlation and interferometry techniques to track glacier movement. These measurements are based on the observations of optical and radar instruments launched by several space agencies to observe the Earth in the last 45 years such as the Landsat/NASA program or the European program Copernicus with the Sentinel/ESA satellites. The CryoDyn team uses these measurements to study annual and seasonal variations in ice flow in order to understand the mechanisms governing these changes and to establish the mass balance of ice sheets or glaciers.
