Abstract
In March 2021 a field experiment was conducted in the high Alpine test site Woergetal in the Austrian Alps, exploring the application potential and performance of snow mass (snow water equivalent, SWE)...
The estimation of snow parameters, such as snow water equivalent (SWE) and liquid water content (LWC), is an important task to support the water management and avalanche warning applications. The purpose of this study is twofold: in the first case we intend to retrieve the SWE using X-band SAR data, in the second case we want to retrieve LWC from X- and C-band SAR data. Many measurement...
The area extent and duration of surface melt on ice sheets are important parameters for climate and cryosphere research and key indicators of climate change. The surface melting / refreezing condition is essential information for modelling glacier hydraulics and the surface energy budget. Data on surface meltwater production are also crucial for estimating changes in the subglacial water...
In an experimental airborne SAR dataset, a complex and heterogeneous scattering pattern was found at the Russel glacier, also known as K-Transect, in western Greenland. In a first analysis, two potential ice types could be classified based on their distinct differences in scattering processes. A first glaciological theory for these two ice types is, on the one hand, temperate ice with low...
