is an Australian partnership between CSIRO, the Bureau of Meteorology and
the Royal Australian Navy. The global ocean model that Bluelink is based on is the
Ocean Forecasting Australia Model (OFAM) which is based on MOM. Observations are assimilated
using the Bluelink Ocean Data Assimilation System (BODAS), an ensemble
Optimal Interpolation (EnOI; Oke et al. 2002; 2006) system that has been
developed under Bluelink. The Bluelink global ocean model and data assimilation
system have been implemented operationally at the Bureau of Meteorology where it is called
OceanMAPS. OceanMAPS produces a seven-day forecast of ocean
conditions daily and assimilates the following observations from
various sources including Argo and SOOP-XBT:
Bluelink also performs ocean reanalyses known as Bluelink ReANalyses
BRAN3.5 is a 20-year reanalysis that assimilates satellite altimetry,
satellite sea-surface temperature and in situ
temperature and salinity from Argo floats and moorings.
The most recent BRAN (BRAN3.5) spans 1/1992 to 7/2012.
- sea-level anomaly (SLA)
- sea-surface temperature (SST)
- in situ temperature (T)
- in situ salinity (S)
The following parameters are outputs of the Bluelink OceanMAPS model and maps
can be found and downloaded
The following parameters are outputs of the Bluelink BRAN reanalysis:
- Sea Surface Temperature (SST)
- Sea Surface Salinity (SSS)
- Sea level anomaly (SLA)
- Surface currents
The BRAN data
in NetCDF format for 1993 to 2012 can be downloaded from an openDAP server.
- Sea Surface Temperature (SST) daily, weekly and monthly
- Subsurface Ocean Temperature at 150m, 400m and depth of 20°C isotherm
The Bluelink products are used for defense, the public good, shipping, oil and gas planning,
search and rescue, and fisheries management. Bluelink data helped support the search for
the missing Malaysian Airplane (MH370).
The model has a global configuration with 1/10° resolution around
Australia. Several boxes exist around Australia's coastline as seen below.
