BLUElink> is a joint Australian government initiative to develop Australia’s first operational ocean forecasting system called OceanMAPS. The project has transitioned to the implementation and trial phase using the infrastructure of the Bureau of Meteorology. OceanMAPS has a global grid with 1/10 by 1/10 resolution in the Australian region (90E-180E, 70S-16N) and uses the Modular Ocean Model version 4 optimised for the NEC SX6. The analysis uses an ensemble based multi-variate optimal interpolation scheme where model error covariances are derived from a 72-member ensemble of intra-seasonal anomalies based on a 12-year ocean only model integration. The scheme has been formulated to assimilate near real-time sea level height anomalies processed from Jason-1, ENVISAT, Geosat Follow-On and Topex/Poseidon and profile observations including Argo, XBT and the TAO array. The operational configuration including the data management of the near real-time observations is reviewed. An analysis of the impact of altimetry and Argo on both the analysis and forecast skill of OceanMAPS during the operational trials is presented.
