Remote Sensing, Model-Derived and Ground Measurements of Snow Water Equivalent and Snow Density in Alaska
Snow water equivalent (SWE) is important for investigations of annual to decadal-scale changes in A and energy-water cycles. Passive microwave satellite-based retrieval algorithm estimates of SWE now sp three decades. SWE retrievals by the Advanced Microwave Scanning Radiometer for the Earth Ob (AMSR-E) onboard the NASA-Aqua satellite ended at October 2011. A critical parameter in the AM gorith...
متن کاملInferring Snow Water Equivalent for a Snow-Covered Ground Reflector Using GPS Multipath Signals
A nonlinear least squares fitting algorithm is used to estimate both snow depth and snow density for a snow-layer above a flat ground reflector. The product of these two quantities, snow depth and density, provides an estimate of the snow water equivalent. The input to this algorithm is a simple ray model that includes a speculary reflected signal along with a direct signal. These signals are t...
متن کاملGround Temperatures under Ski Pistes with Artificial and Natural Snow
Increasing production of artificial snow in ski resorts is controversially discussed, but only few investigations have been carried out systematically to specify the environmental impacts. We measured snow depth and density from groomed ski pistes (runs) with compacted snow and their effects on ground temperatures and timing of snowmelt. We analyzed groomed pistes with and without artificial sn...
متن کاملSpectral reflectance of antarctic snow: "Ground truth" and spacecraft measurements
W IL cr lion depicted in figure 2, had an overall degree of polarization of about 20 percent, but near its inner edge the polarization was considerably less because of the birefringence effect. No change of sign of the polarization was observed in that region. • The 120 parhelion is in horizontally polarized light about 0.2' higher over the horizon and 0.05' closer to the sun than in vertically...
متن کاملSnow scattering signals in ground‐based passive microwave radiometer measurements
[1] This paper investigates the influence of snow microphysical parameters on the enhancement of ground‐based passive microwave brightness temperature (TB) measurements. In addition to multispectral passive microwave observations between 20 and 150 GHz, a 35 GHz cloud radar and a 2‐D video disdrometer for in situ measurements of snowfall were deployed as part of the “towards an optimal estimati...
