Abstract

    Year-round monitoring of atmospheric mercury deposition in wet deposition, aerosol (particulate-bound) and vapor (gaseous elemental) phases. The study is part of an integrated program of research and monitoring on atmospheric deposition in the Lake Champlain Basin coordinated over time with NOAA, University of Michigan Air Quality Lab, the Lake Champlain Research Consortium, the Mercury Deposition Network and the Atmospheric Mercury Network.

  • Title: Concentration and Deposition of Mercury in Precipitation at Underhill, VT, 2004 - 2005
  • Start Date: 2004-01-03
  • End Date: 2005-12-29
  • Description: Measure the concentration of atmospheric mercury deposited from precipitation. These data were collected to investigate what, if any, slight differences in funnel diameter, stick gauge size, etc. would have on deposition measurements.

  • Purpose: Year-round monitoring of atmospheric mercury deposition in wet deposition.
