   Jul 10, 2017 · Snow optical grain radius usually ranges from ∼50 to >1000 μm (Reference Painter, Dozier, Roberts, Davis and Green Painter and others, 2003). These particles create a volume-scattering medium with penetration of radiation into the snowpack, which depends primarily on wavelength and particle size.

   Sep 2, 2022 · The results show that the rough soil surface scattering contribution, including snow attenuation, is around −12 dB at X-band and decreases to −14 dB at 17.2 GHz; higher frequencies such as Ku-band typically experience higher volume scattering and greater attenuation of the surface scattering contributions. Continued studies are required to ...

   Does soil interference affect snow volume scattering?

   • Abstract The sensitivity of synthetic aperture radar (SAR) polarization information to snow depth changes provides new opportunities for regional snow depth retrieval in mountains with thick snow cover. However, interference from soil signals can affect the accurate quantification of snow volume scattering signals.

   Does soil polarization affect snow volume scattering?

   • They successfully estimated snow depth in the mountainous regions of the Northern Hemisphere using the cross-polarization ratio method, creating a new means for the application of polarization characteristics in snow depth retrieval. However, soil signals may affect the accurate quantification of snow volume scattering signals.

   Does snow volume scattering affect snow depth?

   • The snow volume scattering component in vh-polarization is no longer negligible compared to the contribution of the ground surface. The cross-polarization ratio σ 0vh / σ 0vv (in linear scale, converted to dB) shows overall a stronger correlation with snow depth than σ 0vh (Fig. 3, middle and right columns).

   How does snow affect soil purity?

   • (3):(3)βc=σVV°σVH°+σVV°According to this equation, we found that the presence of snow on the soil surface causes an increase in the VH polarization, which in turn reduces the value of βc. This change further affects the products of the mcand βc, decreasing the soil purity.

   Is there an inverse relationship between snowpack scattering and ground scattering?

   • An inverse relationship can occur with site-specific ground, vegetation and snow conditions, if the attenuation of ground scattering by the snowpack is stronger than the scattering contribution from the snowpack 25.

   Nov 1, 2020 · Abstract. Wetness is one of the important physical parameters of snowpack. Its spatial and temporal changes play a key role in snowmelt runoff forecast, regional climate change, and agricultural irrigation. In this study, we proposed a new method to retrieve snow wetness from full-polarimetric synthetic aperture radar (SAR) data.
