The thermal dissipation method to measure sap flow in tree stems can be used with cyclic heating to reduce electricity consumption and/or to account for natural temperature gradients. Nevertheless, errors in sap flow estimation can be introduced because the thermal equilibrium has not been reached at the measurement time. We propose a method to assess this error and to estimate sap flow density. It is based on Granier’s (Ann For Sci, 42:193–200, 1985) non-species-specific calibration. This work… CONTINUE READING
