Southern Ocean State Estimate solution

The links below take you to files containing current results of the Southern Ocean State Estimate (SOSE), including the state variables, air-sea fluxes, and various diagnostics. Be sure to adhere to our disclaimer and terms of use. If you are a new user please let us know that you will be using our product. All users are encouraged to contact us for a description of methodology, file formats, or with any other questions you may have. And please let us know if you require diagnostics not presently hosted on this site.

When using this solution please include the following statement: "Computational resources for the SOSE were provided by NSF XSEDE resource grant OCE130007." Also please cite:M. Mazloff, P. Heimbach, and C. Wunsch, 2010: An Eddy-Permitting Southern Ocean State Estimate. J. Phys. Oceanogr., 40, 880-899. doi: 10.1175/2009JPO4236.1

The matlab function rdmds.m or the python function mds.py can be used to read the output (you will need both the .data and .meta in the read directory)

The model grid can be downloaded here (grid.mat) -- let me know if you prefer it as binary). Some information about the grid.

If you are not experienced closing budgets with MITgcm output I recommend you contact us for assistance.
