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.
