The BOREAS TE-09 team collected several data sets related to chemical and photosynthetic properties of leaves in boreal forest tree species. This data set describes the spatial and temporal relationship between foliage nitrogen concentration and photosynthetic capacity in the canopies of black spruce, jack pine, and aspen. The data were collected from June to September 1994 and are useful for modeling the vertical distribution of carbon fixation for different forest types in the boreal forest.
A guide document which includes more information about this data set can be found at http://daac.ornl.gov/boreas/TE/te09npd/comp/TE09_NITROGEN_PHOTO.txt.
ORNL DAAC maintains information on the entire BOREAS Project.
