Panama leaf water potential census 2015-2019

Abstract

This dataset contains values of leaf water potential from a monthly census of predawn and midday measurements conducted on nine trees in each of two sites in Panama from December 2015 to July 2019. The dataset includes individual measurements that were made with a pressure chamber. The measurements were made on the focal trees to complement concurrent measurements of sap flow. The trees were also intensively measured for leaf-level physiological condition during the 2016 ENSO campaign conducted by NGEE-tropics. A subset of measurements was made on leaves that were sealed in plastic bags and protected from solar radiation before they were collected, such that the measurements assessed branch water potential. The dataset contains a csv file that has columns for the time, location, and value of each measurement. The dataset also contains a metadata file, column description file, and an E-Field log file in the recommended NGEE-Tropic formats.
