A 1-year study (August 2005–July 2006) of the event-based relative collection performance of the MDN modified Aerochem (ACM) sampler, the University of Michigan modified MICB sampler, and the NCON Systems mercury deposition sampler. The samplers were deployed at the Underhill, VT Air Quality Research Facility (VT99), and at locations in WA and WI, too. This dataset includes comparative rain gage data and comparitive sample analysis data.1) Assess the relative performance of 3 collector types in a rural location. 2) Identify the most suitable collector for long-term monitoring of mercury in precipitation in the Lake Champlain Basin. 3) Identify reasons for differences in collector performance that could lead to improved collector designs and 4) Develop transfer functions for normalizing data obtained from the different collector types and laboratories.Z1106_2327_2J2P4YVMC.1106.2327mySQLEric Miller. 2009.
