The OASIS coupler allows for synchronised exchanges of coupling information between numerical codes representing different components of the climate system. Currently, it is being developed by Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS) and Centre National de la Recherche Scientifique - Institut Pierre Simon Laplace (CNRS-IPSL).

OASIS3-MCT is the latest version of the OASIS coupler interfaced with the Model Coupling Toolkit (MCT) from the Argonne National Laboratory. It offers today a fully parallel implementation of coupling field regridding and exchange.

How to apply for support:

2020: In the first call, two months of Dedicated User Support were granted to NERSC (Norway) as ESiWACE2 Service 2 on OASIS3-MCT.

2022: In the second call two months of Dedicated User Suppoirt were granted to the UK Met Office to further develop 3D ocean/biogeochemistry coupling in NEMO with MEDUSA.

In addition, trainings on OASIS3-MCT are also offered regularly as face-to-face trainings and Small Private Online Courses (SPOCs). See also our story on efficiently learning how to use the OASIS coupler. More information about the next course sessions, when planned, can be found on the OASIS3-MCT training page.
