`ACC_mitgcm_config`

Contains MITgcm configuration files for the coarse and fine model, including their spinups. This includes the compilation code and namelists.

`ACC_particle_experiments`

Contains Python scripts for the Lagrangian simulations carried out with Parcels (experiments with a tracer patch, and with particles initialized on a lattice), and analysis scripts pertaining to these simulations and their output.

`data_processing`

Contains scripts and notebooks for processing the data. This includes creating coarsened fields, computing discrete derivatives, and computing the quantities necessary for the LS parameterization.

`idealized_experiments`

Experiments using the idealized set-up.

`kernels`

Functions used by Parcels to drive the Markov models.

`misc`

Contains a PDF copy of the documentation for MITgcm's ACC channel simulation. At the date of writing, this documentation is also available online at https://mitgcm.readthedocs.io/en/latest/examples/reentrant_channel/reentrant_channel.html.

`tools`

Miscellaneous helper functions.

`verification`

Notebooks that inspect the MITgcm model output.

`visualization`

For some of the figures in the manuscript. Others are located under the ACC_particle_experiments > analysis notebooks, or under idealized_experiments/3D_3D_idealized_isopycnal_Markov1.ipynb
