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, where complex topography and meteorology, heavy precipitation, and extreme cold. Instruments selected for evaluation included the Aerochem Metrics Model 301 wet/dry deposition collector, the Belfort Model 5-780 weighing rain gage, and the U.S. Geological Survey designed 46-cm bulk samplers.
