the importance of sap flow sensor calibration
The calibration of sensors is one of the principle activities of scientists across all research fields. Calibration is critical for accurate and precise measurements. However, it is common for sap flow sensors to never be calibrated. That is, it is an exception when a published paper mentions that a sap flow sensor was calibrated.
But recent research has shown that uncalibrated sap flow sensors have an average error of 34%. Such a significant amount of error will have important ramifications for the analysis and interpretation of sap flow data and research.
