Sap Flow Analyzer

The Sap Flow Analyzer (SFA) is an R Shiny App to process sap flow data recorded with Heat Field Deformation (HFD) instruments. The app allows to clean the data, determine k-values, calculate sap flow per section and density as well as to estimate sap flow rates and tree water use. A detailed description of the methodology can be found in Wimmler et al. (in prep.).
