Snowpacks collect atmospheric deposition throughout the snowfall season and offer a unique opportunity to obtain a composite sample of the chemistry of most of the annual precipitation at high elevations [> 1,800 meters]. The purpose of the snowpack network is to determine annual concentrations and depositional amounts of selected nutrients and other constituents in snow resulting from atmospheric deposition, determine long-term trends in these concentrations, and to support investigations of the effects of atmospheric deposition on local and regional ecological systems. Since 1993, the project has become the most expansive and comprehensive snowpack-chemical monitoring network of its kind.
