Simple tree model for xylem and phloem sap flux calculations following Hölttä et. al., (2006) and Nikinmaa et. al., (2014)
The root uptake is modelled according to Volpe et. al., (2013)
The gas transport module is based on Hölttä and Kolari (2009) and stem gas transport model by Jani Anttila.
The documentation, instructions to run the model and description of the modelled system can be found from tree-box-model.readthedocs.io
