Abstract

Remote sensing techniques using combined concurrent measurements of near-infrared passive reflectance and millimeter-wave radar backscatter were used to estimate surface snow properties. The effectiveness of the procedure was tested using 400 combinations of surface parameters. Results indicate that a neural network approach using near-infrared and millimeter-wave measurements show promise in estimating surface snow parameters. Since the spatial resolutions attainable at near-infrared and millimeter-wave spectral regimes are different, a combination of these inversion algorithms has the potential to characterize the spatial distribution of free-water content of snow, while also providing accurate estimates of grain size and surface roughness.
