Atmospheric Mercury Network (AMNet)

At the 2009 Fall Meeting in Saratoga Springs, the NADP Executive Committee accepted the Atmospheric Mercury Network as an official NADP network. Therefore, methods will be finalized within the framework of NADP’s open committee structure.

The Atmospheric Mercury Network (AMNet) established this network of monitoring stations for the purpose of measuring atmospheric mercury fractions which contribute to dry and total mercury deposition. Sites will collect concentrations of atmospheric mercury species from automated, continuous measuring systems, concentrations of total mercury in precipitation, and meteorological measurements. Data will be collected with standardized methods, with quality assured data archived in an online data base.

AMNet has specific objectives:

  • measure atmospheric mercury concentrations of gaseous oxidized, particulate-bound, and elemental mercury in select locations;
  • offer high-quality measurement data to estimate dry and total deposition of atmospheric mercury to other researchers;
  • standardized operational methods so that instruments are being operated consistently;
  • provide internal and external quality assurance;
  • provide the data management capability and access; and
  • provide field support through an experienced site liaison.

As with other networks, NADP welcomes the participation of other organizations and scientists. To truly understand the mercury problem, more monitoring information is needed. Therefore, we would welcome anyone who is interested in learning more about NADP, the AMNet, or has questions about data access to contact either Mark Olson ( 608.335.4232) or David Gay ( 217.244.0462) for more information.
