Data on the effects of elevated carbon dioxide and ozone on carbon and nitrogen metabolism in the foliage and sapwood of trembling aspen, paper birch, and sugar maple at the Aspen FACE (Free-Air Carbon Dioxide Enrichment) study site

This data publication includes biochemical parameters as measured in foliage and sapwood from trees included in the Aspen FACE (Free-Air Carbon Dioxide Enrichment) Experiment on the Harshaw Research Farm (renamed the Rhinelander Experimental Forest in 2015), near Rhinelander, WI. Three different clones of trembling aspen, Paper birch and sugar maple trees were exposed to seasonal fumigations of Ozone (O₃), Carbon Dioxide (CO₂), and CO₂+O₃ in open-air rings between 1998 and May 2009. Data includes free polyamines, free amino acids, soluble ions, chlorophyll and soluble protein and were analyzed by HPLC, ICP, and spectrophotometer. Foliage samples were collected from 2006-2008 and sapwood samples were taken in 2009.
The Aspen FACE Experiment was a collaborative and multidisciplinary study to examine how different plant attributes (e.g. metabolism, anatomy, physiology, growth, development, wood growth, root and soil characteristics) responded to increased ozone and carbon dioxide concentrations. The data collected could be used in climate change models to show the potential impacts of those plant responses on the structure and function of northern forest ecosystems.
