ABSTRACT
Both the European Centre for Medium-Range Weather Forecasts and the National Centers for Environmental Prediction (NCEP) have performed multiple atmospheric reanalyses using a static model and assimilation scheme while ingesting all available quality controlled observational data. However, no long-term reanalysis using a high horizontal and vertical resolution ocean model currently exists that is a corollary to the atmosphere. To fill this void, the Naval Research Laboratory is performing a 1993-2009 ocean reanalysis using the 1/12° global HYbrid Coordinate Ocean Model (HYCOM) fully two-way coupled to the Community Ice CodE (CICE) and employing the Navy Coupled Ocean Data Assimilation (NCODA) scheme. The system will be forced with atmospheric output from the NCEP Climate Forecast System Reanalysis and the observations. The reanalysis will begin in 1993 because of the advent of satellite altimeter data that will constraint the oceanic mesoscale.
