Description:
During the last 15 years, operational oceanography systems have emerged in several countries
around the world. This emergence has been largely fostered by the GODAE experiment, during
which each nation engaged in this activity have organised partnership and constructive
competition. This trans-national coordination was very beneficial for the development of
operational oceanography, leading to economies of scales and more targeted actions. Today,
several systems provide routine real-time ocean analysis and forecast and/or reanalysis products.
They are all based on (i) state-of-the-art primitive equation baroclinic Ocean General Circulation
Model (OGCM) configurations, either global or regional (basin-scale), with resolutions that
range from coarse to eddy resolving and (ii) data assimilation techniques whose complexity
ranges from simple analysis correction to advanced 4D variational schemes. They assimilate
altimeter sea level anomalies, remotely sensed SST such as GHRSST products and in situ
profiles of T and S, including ARGO. Some systems have implemented downscaling capacities
in specific regions of interest including shelf/coastal seas. Some also have implemented coupling
with the atmosphere and/or the prognostic sea ice in polar regions. They are the GODAE system
in operation. They are reviewed in this paper. The GODAE system discussed here include: (1)
BLUElink OceanMAPS, (2) C-NOOFS, , (3) ECCO, (4) FOAM, (5) HYCOM/NCODA, (6)
MERCATOR, (7) MFS, (8) MOVE/MRI.COM, (9) NLOM/NCOM, (10) NMEFC, (11) RTOFS
and (12) TOPAZ.
