Beschreibungen/Notizen

• Credible predictions of climate change depend in part on predictions of future CO sub(2) concentrations in the atmosphere. Terrestrial plants are a large sink for atmospheric CO sub(2) and the sink rate is influenced by the atmospheric CO sub(2) concentration. Reliable field experiments are needed to evaluate how terrestrial plants will adjust to increasing CO sub(2) and thereby influence the rate of change of atmospheric CO sub(2). Brookhaven National Laboratory (BNL) has developed a unique Free-Air CO sub(2) Enrichment (FACE) system for a cooperative research program sponsored by U.S. Department of Energy and U.S. Department of Agriculture, currently operating as the FACE User Facility at the Maricopa Agricultural Center (MAC) of the University of Arizona. The BNL FACE system is a tool for studying the effects of CO sub(2) enrichment on vegetation and natural ecosystems, and the exchange of carbon between the biosphere and the atmosphere, in open-air setting without any containment.
