CIME (Advanced)

The Combined Model Components form the coupled CESM through a shared common set of tools and infrastructure and coupling framework. Here we describe the Common Infrastructure for Modeling the Earth otherwise known as CIME, and other coupling frameworks.

Common Infrastructure for Modeling the Earth (CIME)

The Common Infrastructure for Modeling the Earth is a python-based framework that is shared between CESM3 and other modeling center efforts to ensure efficient coordination of model development. The schema below shows some of the science benefits and organizations that are using the CIME infrastructure.

Earth System Modeling Framework (ESMF) Coupling

The CESM3 coupling is performed through the Earth System Modeling Framework (ESMF) National Unified Operational Prediction Capability (NUOPC) framework. More details on NUOPC can be found at https://earthsystemmodeling.org/nuopc/ . The schema below shows the new CESM configuration and coupling with NUOPC.
