Biogeochemical Southern Ocean State Estimate solution

The links below take you to files containing the Iteration 105 solution of the Biogeochemical Southern Ocean State Estimate (B-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, assistance closing budgets, or with any other questions you may have. And please let us know if you require diagnostics not presently hosted on this site.

B-SOSE is a contribution of the Southern Ocean Carbon and Climate Observations and Modeling project (SOCCOM) program. SOCCOM is an NSF-sponsored program focused on unlocking the mysteries of the Southern Ocean and determining its influence on climate.

Most files processed into netcdf form using xmitgcm with grid information included. Let us know if you prefer it in a different format. Some information about the grid.

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: A. Verdy and M. Mazloff, 2017: " A data assimilating model for estimating Southern Ocean biogeochemistry." J. Geophys. Res. Oceans.,  122, doi:10.1002/2016JC012650.
