Although seasonal snow cover is widely recognized as a critical water resource, accurate SWE assessment is still challenging when considered at an operational level, especially in regions characterized by complex topography [1]. SWE retrieval methods based on polarimetry are inherently linked to the assumption of specific models of the snowpack, [1], [2], [3],[4], [5]. Such approaches can turn...
Spaceborne differential SAR interferometry has been demonstrated to potentially allow for snow water equivalent (SWE) change measurements on a spatial scale, resolution, and accuracy unprecedented by other sensor concepts [1][2]. However, its operational use is hindered mainly because of: i) low coherence areas resulting from temporal decorrelation, largely complicating a robust phase...
Ice sheets play a critical role in regulating global climate and sea-level rise. To enhance the accuracy of climate modeling and predictions, it is essential to comprehend the intricate processes of snow accumulation, transformation, and melting that transpire on ice sheets. A fundamental component of monitoring ice sheets involves identifying distinct layers or units within the snowpack,...
For the first time in Earth observation, the BIOMASS mission will collect polarimetric P-band SAR data from space that could help monitor large-scale subsurface areas of Antarctica. Indeed, such electromagnetic frequencies penetrate dry ice and snow and may provide information about the stratification and depths of cryospheric elements. This capability will provide easily interpretable...
A key uncertainty in mass balance studies of glaciers and ice sheets is still today the density for the volume-to-mass conversion. This is not only reported on a global scale [1] but also for recent local studies [2], where even the presence of in situ measurements can only partly capture the density uncertainty [3]. The volume-to-mass conversion factor can span a wide range from 0 to 2000 kg...
