Abstract: The Coupled Ocean/Atmosphere Mesoscale Prediction System – On-demand System Version 2.2 (COAMPS-OSŪ v2.2) and the Earth System Modeling Framework (ESMF) provide Fleet Numerical Meteorology and Oceanography Center (FNMOC) and Naval Oceanographic Office (NAVOCEANO) with the ability to forecast the coupled atmosphere-ocean environment within focused domains and at moderate to very high resolutions. In COAMPS-OSŪ v2.2, the atmospheric component of model is linked to the ocean component (the Navy Coastal Ocean Model, NCOM) in 2-way coupled mode via ESMF. Observed data are assimilated in the atmospheric model using the Navy Atmospheric Variational Data Assimilation System (NAVDAS) and the ocean model via the Navy Coupled Ocean Data Assimilation System (NCODA). This capability, developed by the Naval Research Laboratory, will run with the same model algorithms and data at both FNMOC and NAVOCEANO, ensuring similar outputs from both production centers. The end-to-end transition process will be described, including development, validation, and operational implementation, checkout, and testing. Challenges encountered during this transition will be detailed including differing validation metrics for atmospheric and oceanographic variables, and the development of a multi-center concept of operations.
