OSMOSIS is expected to deliver significant improvements to the Ocean Surface Boundary Layer (OSBL) in the Nucleus for European Modelling of the Ocean (NEMO) model — a sophisticated framework for oceanographic and climate studies developed by the modelling community.

New parameterisations of turbulent mixing and sub-mesoscale re-stratification, generated through OSMOSIS, will be implemented into NEMO. Their impact on the OSBL, each other and ocean circulation will be thoroughly evaluated using idealised model settings and under varying scenarios.

The new parameterisations will subsequently be implemented and reviewed on a global ocean scale through hindcast runs of NEMO. If successful, this will leave a long lasting legacy for the consortium.

Definitive model output from the OSMOSIS consortium will be ingested by BODC and made available via our numerical model data portal.
