    Jun 1, 2024 · According to the study outlined by Lievens et al. (2022), there is a significant correlation between the cross-polarization ratio (CR) and snow volume scattering, with the CR increasing as the snowpack thickness increases. Therefore, the degree of depolarization of a snow-covered surface in the field of SAR snow depth retrieval can be defined ...

    Jul 19, 2021 · Combining ground-measured meteorological data and high resolution digital elevation models, we show that the forward scattering peak of snow leads to a strong local redistribution of incident terrain reflected radiation. In particular, the effect of multiple terrain reflections is enhanced.

    Jul 4, 2022 · Key Points. Microwave scattering by snow is reformulated as a function of snow physical and measurable variables only, without empirical adjustments. Two new metrics, microwave grain size and polydispersity, are introduced to describe the length scale complexity of the snow microstructure.
