Coupling

As shown on the model architecture page, we couple the model components using NUOPC with the CMEPS mediator. NUOPC is an interoperability layer for ESMF which standardises how model components interact. See discussions here and here for more information.

How to determine which fields are coupled

The coupled fields and remapping methods used are recorded in the mediator log output file and can be found with grep '^ mapping' archive/output000/log/med.log; see here for how to decode this. See the Configurations page for details on how the coupling is determined.
