Sap flow data from San Lorenzo, Panama (PA-SLZ) from January - June 2020

This data package contains sap flow data from the NGEE Tropics site in San Lorenzo, Panama (PA-SLZ) from 01 January 2020 to 01 June 2020. Sap flow measurements quantify plant-level transpiration, which varies across spatial and temporal scales. It is a key trait in understanding plant hydraulic functioning. Here sap flow was measured using ‘Granier-type’ thermal dissipation probes. Raw data downloaded from the data logger is in the 'Raw data' folder as a CSV file. The data was processed using the AquaFlux package in R. R code for preparing the data for use in AquaFlux is in the 'R code for pre-processing data folder'; it is saved as a text file that can be copy and pasted into R. Each core sap flow tree has two sensors. The data was processed for each sensor as well as for each tree. These processed data files are in the 'Processed data' folder as CSV files. Documentation for the Granier sensors and AquaFlux package is in the ‘Manuals’ folder as PDF files. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival Acknowledgement: Funding for NGEE-Tropics data resources was provided by the U.S. Department of Energy Office of Science, Office of Biological and Environmental Research.
