A FACE Experiment in a Deciduous Forest
The Oak Ridge Experiment on CO2 Enrichment of Sweetgum is a Free-Air CO2 Enrichment (FACE) experiment at the Oak Ridge National Laboratory in Tennessee, USA. We are testing critical hypotheses about the responses of a closed-canopy deciduous forest to the atmospheric CO2 concentrations of future decades. The research is sponsored by the U.S. Department of Energy.
