Description
Summary:The necessary removal of the on-disk coupling procedure of the ocean zoom surface fields in the GEOMAR OpenIFS-NEMO-AGRIF coupling (FOCI) required the upgrade of both NEMO and OpenIFS interfaces. The inexpensive OASIS coupling that has been set up allowed to increase the OpenIFS horizontal resolution to 25Km. The CPU cost of the coupled system, that includes the North Atlantic zoom AGRIF, is estimated to approximately 30 time less than the CPU cost of the corresponding global ORCA12 based configuration.
