Accurate measurement of snowfall is critical to the assessment of acidic deposition trends, particularly in areas where snow represents 30 percent or more of the annual precipitation. Such areas include the intermountain west, characterized by complex topography and meterology, heavy precipitation, and extreme cold. A study was conducted in the spring of 1987 to evaluate the performance of selected equipment in complex high altitude terrain. The instruments selected for evaluation included the Aerochem Metrics Model 301 wet/dry deposition collector, Belfort Model 5780 weighing rain gage, and the U.S. Geological Survey designed 46-cm bulk samplers. All instruments were installed on a platform above the expected snowpack at the University of Denver High Altitude Laboratory, located near Mount Evans in Colorado.
