Long-Term Ecological Research (LTER)/CDR027: Atmospheric Deposition (Wet and Dry) at Cedar Creek Natural History Area

LTER - Long-Term Ecological Research Program/Cedar Creek Natural
History Area (CDR)

LTER/CDR027 [Summary adapted from the LTER Core Data Set Catalog]:

Precipitation is collected continuously in an Aerochem-Metrics
wet-only sampler. Solutions are analyzed weekly for pH and inorganic
cations and anions. Ambient air gases and particulates are collected
on a low-volume filterpack sampler. Filters are analyzed weekly for
SO2, HNO3, and inorganic cations and anions. Methodology has changed
during the study.

The Cedar Creek Natural History Area (CCNHA) is a 2200 hectare
experimental ecological reserve operated by the University of
Minnesota in cooperation with the Minnesota Academy of Sciences. CCNHA
is located in Anoka and Isanti Counties north of Minneapolis/St. Paul.
The site was established in 1940, was designated a National Natural
Landmark by the National Park Service in 1975. In 1977 it was included
as an Experimental Ecology Reserve in a proposed network, and in 1982
it was one of 11 sites in the U.S. selected by the National Science
Foundation for funding of LTER.
