Snow water equivalent (SWE) storage is critical parameters of the water cycle and may be important indicators of climate change. Despite their importance in the seasonal and regional terrestrial water cycle, SWE is currently poorly characterized in space and time. We develop a method for observations of these parameters using P-band signals of opportunity (SoOp) concept to measure the SWE. Effect of wet snow on the measurement is analyzed through modeling and it is found that for wet snow, the phase of the SoOp measurement becomes correlated to snow depth while for dry snow, phase is correlated to the Snow Water Equivalent (SWE). In addition, qualitative data analysis from two different site for a proof-of-concept experiment is shown in this paper.
