Tumbarumba Gas Exchange

This dataset consists of leaf gas exchange measurements made at the Tumbarumba eddy covariance site in NSW, Australia. Measurements were made during three five-day campaigns in November 2001, February 2002, May 2002. Measurements were made on the overstorey trees (Eucalyptus delegatensis) accessed using a 20-m tall cherry picker. Each day we measured about 4 A-Ci / A-PAR curves, interspersed with spot measurements of photosynthesis and stomatal conductance at ambient light, temperature and humidity. Leaves were tagged during measurements and cut at the end of the day. Specific leaf area, leaf N and P content, and Chl content were determined.
