Reflectivity of snow

WebThe fundamental principle behind the remote sensing of snow through reflectometry is the comparison of the signals that have been reflected off of snow (reflected signals) to signals directly from the satellite (direct signals). To apply this method, the following assumptions have been made: 1. The reflection is specular. 2. WebFeb 10, 2024 · Meanwhile, this paper reviews the research status of spaceborne GNSS-R and other signal of opportunity reflection remote sensing (SoOP-R). GNSS-R's applications on soil moisture, vegetation, soil freeze-thaw monitoring are focused on, while the research status of the latest SoOPR technology in root zone soil moisture and snow water …

WebMar 1, 2001 · This led us to discover that the snow reflectance was strongly affected by the texture of the uppermost layer of the snow surface. Introduction Snow cover has at least two important roles in global warming. Its first role is its high reflectivity to solar radiation. WebIn this paper, a method for estimating snow pressure reflection coefficient based on non-contact ultrasound examination is described. A constant frequency and air-coupled ultrasound pulses were used in this study, which incorporates a parametric method for reflected energy estimation.
