For annual estimates of wood, litter, and fine root production, as well as LAI, LAD, APAR, and peak seasonal fine root standing biomass for several FACE sites, including ORNL, please see NPP synthesis research. Please note that the site NPP data listed above (2008) supercedes the values published in the synthesis research for the ORNL FACE.
