This report presents the global ocean/sea ice configuration at eddy-resolving resolution developed at CMCC, and describes numerical re- sults from the first simulation. The model configuration, based on the NEMO system, has 1/16◦ horizontal spacing at the equator and uses 98 vertical levels. So far this is the highest resolution implemented in a global NEMO domain. The numerical experiment has been performed on the MareNostrum cluster located at the Barcelona Supercomputing Center (within the framework of the ENS4OCEAN project awarded in the PRACE 8th Regular Call). This simulation represents a major step forward in high resolution ocean modeling.
