The amount of water in a snow pack can be described by the snow water equivalent (SWE). SWE is a crucial parameter for hydrological models, for example, for flood predictions. Previous studies have shown that the interferometric phase between two repeat-pass synthetic aperture radar (SAR) measurements can be used to determine the change in SWE. However, a limitation of this method is phase wraps. ...Show More
