Leaf gas exchange survey by leaf age, Feb2017, PA-SLZ: Panama

Author(s): Serbin S; Wu J; Ely K; Rogers A

Dataset Information


Site Name: Bosque Protector San Lorenzo (Fort Sherman)

Variables: Leaf gas exchange

Date Range: Feb. 16, 2017 - Feb. 22, 2017

Description: Leaf gas exchange survey measurements on in situ sunlit canopy leaves of four tree species from the San Lorenzo Canopy Crane Site in Panama in February 2017. Multiple measurements were taken on young, mature and old leaves at 3 or 4 time points for each species (early morning, mid-morning, solar noon, afternoon) over 4 days. This data was collected as part of the 2017 BNL–STRI leaf traits by age campaign. See related datasets for other measurements made as part of this campaign including leaf water potential, leaf spectra, sap flow, leaf mass per area, other gas exchange measurements and leaf chemistry. Note: A corrected version of the data file was posted on October 9, 2018.


Methods Description: Corrections made as required per logged remarks and notebook entries. QC column in datafile flags log points considered bad data. Bad data is attributed to failure to reach stable conditions in the leaf chamber, or rates below detection. Any result with negative A, Ci or conductance is flagged as bad data. See included pdf for a full description of the survey gas exchange methods.
