UKESM component models

UKESM1 will be built on around the physical global atmosphere-ocean climate modelling system used at the Met Office, HadGEM3. This uses the NEMO ocean model and the CICE sea-ice, as well as the JULES land surface model, with TRIFFID dynamic vegetation. In addition, UKESM will simulate atmospheric chemistry and aerosols using UKCA, and marine biogeochemistry with MEDUSA. Dynamic ice-sheets wil be provided by the BISICLES model. The interface between the various submodels will use the OASIS coupler.

Coupling the models and evaluating and tuning the results is the responsibility of the UKESM core team.
