Overview of the Navy Coupled Atmospheric and Ocean Modeling Systems

Commander, Naval Meteorology and Oceanography Command (CNMOC) runs oceanography and meteorology global, regional and coastal models to provide the unique naval environmental prediction capability demanded by warfighters. The systems are run operationally at all levels of classification, are tailored and optimized to support Navy and DOD operations anytime and anywhere around the world, and are developed under the Department of Defense Information Assurance standards, filling a unique and demanding role in the world of operational NWP. The development and maintenance of the Navy's coupled global and mesoscale modeling systems is the responsibility of the Naval Research Laboratory (NRL) Marine Meteorology Division (MMD), who work closely with Fleet Numerical Meteorology and Oceanography Center (FNMOC) to transition these capabilities into operations. Outputs from these systems drive downstream applications such as the Navy Aerosol Analysis and Prediction System (NAAPS), the Naval Observatory's universal timekeeping mission, electromagnetic propagation, and air and ship routing. This presentation will describe the current modeling and data assimilation suite, and our plans for the future, including our new global coupled modeling capability and development of a next-generation unified atmospheric model.
