Ice cover on subarctic lakes is an important indicator of climate change at local-or regional scales. This study proposes a new approach for classifying altimetry data from Jason-2 and SARAL/ Altika satellite missions to characterize surface states of subarctic lakes. It focuses on Great Slave Lake (Canada) during freeze-up and thaw periods. For th...
The presence of heterogeneous targets, such as ice, remains a major challenge for the use of altimetric data over inland water bodies. Jason-2 and SARAL/Altika satellites use retracking algorithms designed for oceanic waveforms to retrieve water levels from altimeter measurements. Nevertheless, the accuracy of these approaches need to be assessed o...
Owing to its temporal resolution of 10-day and its polar orbit allowing several crossings over large lakes, the US National Aeronautics and Space Administration (NASA) and the French Centre National d'Etudes Spatiales (CNES) missions including Topex/Poseidon, Jason-1/2/3 demonstrated strong capabilities for the continuous and long-term monitoring (...
