Description:
The manual (user's guide) describes the quality assurance plan and operations protocols for a comparative study of snow collection instruments being conducted on Mt. Evans. Instruments to be compared include the Aerochem Metrics Model 301 wet/dry deposition collector, the Belfort Model 780-5 weighing rain gage, and 18 inch-diameter flanged bulk samplers. In addition, ground measurements are made to provide a 'ground truth' standard. Primary project objectives include assessment of operational reliability, estimation of interinstrument and temporal variability, comparison of water equivalent and matrix chemistry between the collection devices and ground measurements, and recommendation of instruments and sampling intervals for future high altitude, complex terrain monitoring.
