BOREAS TE-09 PHOTOSYNTHETIC RESPONSE DATA
Get Data

Summary:

The BOREAS TE-09 team collected several data sets related to chemical and photosynthetic properties of leaves. This data set describes (1) the response of leaf and shoot-level photosynthesis to ambient and intercellular CO2 concentration, temperature, and incident PAR for black spruce, jack pine, and aspen during the three IFCs in 1994 in the NSA; (2) the response of stomatal conductance to vapor pressure difference throughout the growing season of 1994; and (3) a range of shoot water potentials (controlled in the laboratory) for black spruce and jack pine.

A guide document which includes more information about this data set can be found at http://daac.ornl.gov/boreas/TE/te09prd/comp/TE09_Photo_Resp.txt.

ORNL DAAC maintains information on the entire BOREAS Project.
