The Sap Flow Analyzer is released!

We are pleased to introduce the Sap Flow Analyzer, a free tool to analyze sap flow rates and tree water use from heat field deformation (HFD) instruments. It has been developed by Marie-Christin Wimmler from our group, also implementing the ideas of other sap flow specialists working worldwide. It is designed to ensure maximum accuracy and reproducibility of sap flow estimates by featuring diagnosis diagrams, regression models and different approaches for upscaling sap flow to whole-tree water use. The Sap Flow Analyzer is provided as an R Shiny app, constituting a user-friendly application, which has also been demonstrated by the user trial included in the study.
