DescriptionSnow is a major source of water in Western United States. Data on snow depth and average snowpack density are used in mathematical models to predict water supply. In California, about 75 percent of the snow survey sites above 2750-meter elevation now used to collect data are in statutory wilderness areas. There is need for a method of estimating the water content of a snowpack in inaccessible locations by remote means. If snow albedo can be measured from aircraft and these measures correlated with snowpack density, we should be able to estimate density remotely. But a correlation must first be established from ground-based observations. This paper reports a study of albedo measured 1 meter above the snow and the correlation of these measurements with snowpack density. The study was done at the Forest Service's Central Sierra Snow Laboratory, Soda Springs, California. The findings have application for developing a method for remote sensing of snow density.
