Abstract :
The combination of interferometry and polarimetry (PolInSAR) is a promising candidate for estimating the snow volume using the Random Volume over Ground model (RVoG). The model was originally developed for forest height determination using L-band [1]. The adaption of the RVoG model to snow is not straight forward due to the thin volume of snow and the highly varying penetration depth of X-band microwaves. In this paper we show parameter ranges and recommendation where the RVoG model might work, together with results of interferometry (InSAR) and polarimetric SAR (Pol-InSAR) using TerraSAR-X and TanDEM-X SAR acquisitions.
