Visible And Infrared Transmission Through Snow

A primary objective of the SNOW-ONE Field Experiment conducted in Vermont, during January through March 1981 by the US Army Cold Regions Research and Engineering Laboratory, was to initiate the establishment of a comprehensive data base for electromagnetic energy propagation through falling and blowing snow. In addition to transmission, measurements were also made to characterize (a) the meteorological conditions during the snowfall, and (b) snow particle size distributions, shape characteristics and concentration. We present an analysis of visible and infrared transmission measurements made during various snow conditions. Comparisons of the wavelength dependent extinction are also reported.
