The long-term goal is to develop a fully coupled, global, atmosphere-ocean-ice prediction system that can be used for 0-10 forecasts. This goal is to be accomplished by coupling a full-physics, global ocean model to a global atmospheric forecast model; developing, testing, and evaluating software for the necessary supporting infrastructure; and by leveraging related programs to develop an ocean data assimilation capability. This prediction system will be the cornerstone of a vertically integrated program such that it will be used for basic and applied research to study forecast problems in which coupling may be important and it will also be transitioned to 6.4 for evaluation as an operational analysis/forecast system. In operations, it is expected that this system will provide improved capabilities to describe the atmosphere and the ocean at the analysis and forecast times (to 10 days ahead) and to provide high resolution initial and boundary data for the atmosphere, ocean, and ice to a mesoscale coupled data assimilation system.
