Figure 5. Schematic of BLUElink Ocean Data Assimilation System (BODAS). The three
main components are the ocean model and the data assimilation component (“work engines”),
the observational input data (surface forcing, satellite and in situ observations), and the
analysed output fields which are combined with the model to provide now- and forecasts. The
numbers denote the sequence of steps performed during an assimilation cycle. Courtesy Peter

Relocatable ocean atmosphere model
A relocatable, high-resolution, coupled oceanic-atmospheric model
called the Relocatable Ocean-Atmosphere Model (ROAM) is under
development. The ocean component of ROAM is based on a primitive
equations model developed by Walker and Waring (1998) and the
atmospheric component has been adopted from the Colorado State
University (Regional Atmospheric Modelling System; Pielcke et al., 1992).
ROAM will be embedded within the global OFAM model, bringing the
resolution down to 2 km for domains of the order of 100 km x 100 km.
