   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).

   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 depth affect sensitivity to wet snow?

   • Thereby, the sensitivity to snow depth for wet snow is much more uncertain. Strong melt events, with associated high liquid water contents, may cause fluctuations in σ 0vh / σ 0vv as the signal is more strongly reflected and absorbed by wet snow layers 27.

   Does wet snow affect a snow depth retrieval algorithm?

   • Such measurements would support a quantitative assessment of the uncertainty in the snow depth retrievals caused by wet snow, which in turn may result in a correction for snow liquid water content in the retrieval algorithm.

   Does snow depth increase 0vh?

   • Overall, our study aligns well with the scatterometer measurements over a site in Michigan, USA, revealing an increase in σ 0vh with an increase in snow depth 26. However, the scatterometer measurements showed signs of saturation for depths exceeding ~60 cm, which is not observed in the Sentinel-1 measurements.
