The long-term goal of this project is to improve our ability to analyze and predict the upper oceanlower atmosphere environment, using sophisticated techniques that can exploit data from all available sources. This ability is fundamental to meeting DoDs needs for real-time analysis and improved airsea simulation and prediction on a variety of scales, including mesoscale to tactical scale support in littoral environments and on the battlefield. To meet these needs, the Naval Research Laboratory is developing the Coupled OceanAtmosphere Mesoscale Prediction System COAMPS, and has already transitioned the atmospheric prediction system component to operations. The objective of this particular project is to develop the globally-relocatable, three-dimensional multivariate ocean data analysis component of COAMPS, to provide a capability that will 1 provide the best possible initial conditions for the mesoscale ocean forecast model and 2 provide accurate lower boundary conditions for the atmospheric forecast model. The emphasis is on the development of a complete ocean data assimilation capability, where oceanographic data from a variety of sources are assimilated into an ocean forecast model at regular intervals in a dynamically consistent fashion. The ocean data analysis component must be able to analyze all conventionally available data sources, plus incorporate new data such as upper ocean velocity observations from drifter tracks and HF radar.
