Net Primary Productivity (NPP)

This study, funded primarily by the DOE's Office of Science, Biological and Environmental Research and the National Science Foundation, was performed by researchers at the Department of Energy's Oak Ridge National Laboratory and several other institutions in the United States and Europe, including Duke Forest FACE and ASPEN FACE in Wisconsin. Their work revealed that the response of forest NPP to ~550 ppm CO2 was remarkably similar across a broad range of productivity, with a stimulation at the median of 23%.

Please note that NPP data published in 2008 supercedes these data for the ORNL FACE.
