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

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.

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.

Experiments using the idealized set-up.

Functions used by Parcels to drive the Markov models.

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.

Miscellaneous helper functions.

Notebooks that inspect the MITgcm model output.
