Model code used for the paper: "When do plant hydraulics matter in terrestrial biosphere modelling?" The model is the extension of the terrestrial biosphere model T&C (Fatichi et al., 2012, 2019) including four variants of plant hydraulics The source code is located in the folder /T&C_Code The meteorological input data are located in the folder /Inputs Example model parameters are included in a .m file with the name convention MOD_PARAM_[site] To run the model run the file [site]_GO The model was tested with MATLAB 2023a: Necessary dependencies: The Statistics and Machine Learning Toolbox References Fatichi, S., Ivanov, V.Y. and Caporali, E., 2012.
