AB: Realistic high-resolution ocean and ice components of a future global coupled air/ocean/ice model are being developed, tested, run, and evaluated for use in future synoptic and climate prediction systems. The ocean model is the Parallel Ocean Program (POP); it is configured on a displaced North Pole grid to allow the inclusion of the Arctic, it has a horizontal spacing of 0.1$^\circ$ at the equator and 40 vertical levels, and has an active mixed layer. It is forced with synoptic surface forcing whenever possible. Quantitative evaluations of the two-decade simulation will be presented with particular focus on the mean characteristics of the general circulation and comparisons of the surface variability from data sets with global or near-global coverage such as satellite altimeters and surface drifting buoys. Model biases will be addressed along with efforts to improve unrealistic aspects of the simulation. The inclusion of a dynamic/thermodynamic ice model, such as the Los Alamos National Laboratory CICE model, will improve the realism of the ocean model. Towards this end we are testing a global coupled POP/CICE model at eddy-permitting resolution in the first instance. CICE fields will be compared with satellite data and available observations.
