Mercury Deposition Program

Project Description
The Mercury Deposition Network (MDN) is a national database of weekly
concentrations of total mercury in precipitation and the seasonal and
annual flux of total mercury in wet deposition. The MDN is a part of
the National Atmospheric Deposition Program (NADP) Network.

The MDN began a transition network of 13 sites in 1995. Beginning in
1996, MDN became an official network in NADP with 26 sites in
operation. Over 30 sites were in operation during 1998. The MDN is
anticipated to operate for a minimum of five years and will be managed
at the NADP Coordination Office.
