Liquid Water Content and Chemical Composition in Clouds at Whiteface Mountain, NY
Nenad Aleksic1 and James Dukett2
The objective of this study was to assess the relationship between acidity of clouds and cloud physical parameters at a high elevation site, Whiteface Mountain, in the Adirondack Park, NY. Prior studies at Mt. Brocken /Harz in Germany indicated that ionic composition of clouds is predominantly determined by the liquid water content. Utilizing more than a decade long (1994 to 2006) record of cloud water chemistry at Whiteface we investigated if such a relationship also holds for the Adirondacks, as well changes in the measured acidity over this period. This work is conducted by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation with support from the New York State Energy Research and Development Authority and the USEPA Temporally Integrated Monitoring of Ecosystems/Long-Term Monitoring (TIME/LTM) programs.
