Data files describing CO2 concentrations, meteorlogical conditions, and ecosystem responses are posted through the FACE Data Management System maintained by the Carbon Dioxide Information and Analysis Center. We hope this will make our data more accessible to users worldwide and to facilitate cross-site synthesis research and modeling activities.

Sample Inventory

Plant and soil samples were collected and preserved from throughout the duration of the experiment and as part of the final harvest. Much of this material, including green leaves, leaf litter, wood, roots, and soil, is available to qualified users. The inventory is described in the Excel sheet below. Please contact Rich Norby (rjn@ornl.gov) for more information about the samples and your research needs.
