Abstract: The dielectric properties of wet and dry natural snow were studied inthe frequency range of 50Hz to 100 kHz to determine whether measurements made in this frequency range might prove useful in evaluating the water content of snow. Dielectric heating at 20kHz proved a very useful means of modifying the water content from 0 to 30% byweight. Six different natural snows were used in these experiments. Meltwater was analyzed for conductivity, pH, and impurity content. In addition to developing information on the dielectric properties of wet and dry snow, we measured the changes produced in dry snow by altering its density over the range of 0.11 to 0.66 g/cm^3. Details of the experimental technique and the data obtained are fully reported. Our results do not lead to optimism about the usefulness of measurements in this frequency range alone for the determination of water content. NOTE: This file is large.
