Abstract: Measurements have been made to study the effect of changes resulting from natural aging processes for saline ice and snow on radiometric brightness temperature. The microwave measurements have been made as a function of incidence angle and polarization for frequencies of 10,33.6 and 85 GHz. The experiments are performed on saline ice and snow formed under ambient environmental conditions in an outdoor pond located at the Cold Regions Research and Engineering Laboratory (CRREL), Hanover, N. H., U. S. A. Snow and rain were prevented from reaching selected parts of the pond by interposing a movable cover. Measurements described are microwave temperature at 10 GHz and ice and snow thickness. Random sampling techniques are used to select sites for measurement within the pond area and to determine appropriate sample sizes for future experiments. These studies contribute quantitative information toward understanding the relationship between the properties of saline ice and snow and microwave brightness temperature.
