A coupler is a software package that allows synchronised exchanges of coupling information between numerical models representing different components of the climate system.


OASIS3-MCT is the version of the Ocean Atmosphere Sea Ice Soil (OASIS) coupler interfaced with the Model Coupling Toolkit (MCT) from the Argonne National Laboratory.

Configurations that use OASIS3-MCT

OASIS3-MCT is the coupler used in ACCESS-CM2, ACCESS-ESM1.5 and ACCESS-OM2.


The National Unified Operational Prediction Capability (NUOPC) interoperability layer defines conventions and a set of generic components for building coupled models using the Earth System Modeling Framework (ESMF).

Configurations that use NUOPC

NUOPC is not yet included in any ACCESS-NRI-supported configuration, but will be included in ACCESS-OM3, a configuration currently under development.
