Code used to process and visualise the model output. Model data are available upon request (raw data O(100 Gb)).

page/ directory is for hosting an HTML page with an interactive version of Fig. 1.

Running code

To recreate the same conda environment for running Python code, follow these steps:

1. Install conda
2. Git-checkout or download this repository
3. (on Linux/OSX) Navigate to the repository folder and run

make env

4. Activate the environment

conda activate sergeev2020

5. Run the notebooks manually or use make shortcuts (type make help for help)

Navigation

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.
