Abstract :
The goal of this study is to determine how the shape of snow crystals affects the response of microwave radiation emanating from below and within the snowpack and to determine whether or not the use of spheres is suitable for modeling how this radiation is scattered. This information will be useful in producing more reliable snowcover and snow depth passive microwave algorithms. At the time of this writing, the laboratory analysis and the analysis of the field data are not yet complete, thus the emphasis is on results from modeling
