Dataset Abstract:

Isoprene and photosynthesis data from Mango, growing at the IBAMA camp at Rebiu Jaru, Rondonia. These photosynthesis and isoprene emission data were collected between Feb. 14 and Feb. 16, 1999 at the IBAMA camp at Rebiu Jaru. Data are from a single sun-adapted leaf of mango (Mangifera indica L.) on a large tree growing within the IBAMA compound. Leaf gas exchange measurements were made using a Li-6400 photosynthesis system (LiCor, Lincoln, NE, USA). Light was provided by the Li-6400 LED source. To collect samples of air exiting the leaf cuvette for analysis of isoprene, a t-fitting was placed in the match valve line and samples were withdrawn using a 20 cm3 glass syringe. Samples were then injected directly into an isothermal gas chromatograph constructed at the National Center for Atmospheric Research (NCAR, Boulder, CO, USA). Isoprene was quantified using a RGD-2 Reduction Gas Detector (Trace Analytical, Palo Alto, CA, USA). Calibrations were performed throughout the day, using a 41 ppbv isoprene standard prepared at NCAR and calibrated against a NIST n-butane standard. Mass per unit area of the experimental leaf was 122.5 g m-2.
