Download or read book Electrical Optical and Acoustical Properties of Snow Report of Committee Meeting written by H. Gubler and published by . This book was released on 1982 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements and modeling of the complex dielectric constant of dry and wet snow in the frequency range up to 100 MHz allow accurate (1% accuracy) determinations of the snow wetness in the range of 0.5 to 30% water content as well as particle shape and possible surface parameters. Ground based active radar systems are in use for snow profiling and water-equivalent determinations. Radar radiometers and active radar systems (ground-, aircraft - and satellite-based) show improved performance for snow water-equivalent, wetness, melt-freeze cycle determinations and snow cover mapping. More work is needed to include and correct for the stratification of the snow cover and the structure of the snow. The most important model parameter is the correlation length distribution which can be directly determined from thin sections. Radar measurements are also used for avalanche speed measurements. Visible and near-infrared measurements of albedo are generally well-explained by model calculations, but further observations and modeling efforts are needed. The most important snow parameter is optical grain size; a second important parameter is impurity content. The influence of snow surface structure on the albedo is less than the influence of these other two parameters, but may be important for very low sun angles. Thermal emissivity of snow is about 99%, essentially independent of snowpack parameters.

This book was released on 1980 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the conference a session was held to determine if there is a common ground with respect to the kinds of experiments which should be conducted to determine snow properties. It was intended that this session result in brief statements fof types of experiments, control of conditions necessary, and the proper reporting of data required to make the results of experiments conducted have maximum value to the snow research community. These brief reports cover the subjects of blowing snow, acoustics of snow and acoustical emissions, reflectance and thermal emission, snow classification, sliding ski resistance, electrical properties tests, mechanical properties, tests, measurement of density and velocity in moving snow, and snowpack temperature profiles.
