ICON-O: The Ocean Component of the ICON Earth System Model - Global simulation characteristics and local telescoping capability
Abstract We describe the ocean general circulation model ICON-O of the Max Planck Institute for Meteorology, which forms the ocean-sea ice component of the Earth system model ICON-ESM. ICON-O relies on innovative structure-preserving finite volume numerics. We demonstrate the fundamental ability of...
