Code used to process and visualise the model and other data outputs in order to reproduce figures in the manuscript. Model data are available here. All datasets already preprocessed can be found here.

Notebooks for each individual figure as well as for two data tables are in the code/ directory, while the figures themselves are in the plots/ directory.
