Dear reviewers,

This archive contains:

- A copy of the appendix complementary to the main paper, where additional benchmark tracks are displayed and analyzed alongside further evaluations of the model forecasts.
- A copy of the main branch of the repository containing the code of our benchmark project hosted at https://github.com/mercator-ocean/oceanbench. Please follow instructions to install the package from sources to use this copy of the code instead of the PyPI package.
- Some score computation used in the paper that have not yet been merged into the package. They are available in the "helper_scripts" directory and allow to reproduce the paper results.
- A link to a JupyterLab instance (in which the package is pre-installed) to easily reproduce the evaluation of the GLONET model:
