Sap flux and biophysical measurements of select trees at Panola Mountain Research Watershed, Georgia, 2019
Description
This data release contains a zipped folder with two comma delimited data files and two companion metadata files. The data files are: 1.) sap_flux_data.csv and; 2.) biophysical_characteristics_of_instrumented_trees.csv
The sap flux data were stored in data loggers every 10-minutes for 15 riparian trees. Sap flux was estimated using heat-pulse velocity sensors at three depths into the xylem of each tree. Sap flux estimates in the data release are 30-minute rolling medians which reduces data spikes that are common in high-frequency sap-flux data. The biophysical measurements are properties of the instrumented trees that allow scaling of sap flux to sap flow and total-tree water-use.
