During the last 15 years, operational oceanography systems have been
developed in several countries around the world. These developments have been
fostered primarily by the Global Ocean Data Assimilation Experiment (GODAE),
which coordinated these activities, encouraged partnerships, and facilitated
constructive competition. This multinational coordination has been very beneficial
for the development of operational oceanography. Today, several systems provide
routine, real-time ocean analysis, forecast, and reanalysis products. These systems
are based on (1) state-of-the-art Ocean General Circulation Model (OGCM)
configurations, either global or regional (basin-scale), with resolutions that range
from coarse to eddy-resolving, and (2) data assimilation techniques ranging from
analysis correction to advanced three- or four-dimensional variational schemes. These
systems assimilate altimeter sea level anomalies, sea surface temperature data, and
in situ profiles of temperature and salinity, including Argo data. Some systems have
implemented downscaling capacities, which consist of embedding higher-resolution
local systems in global and basin-scale models (through open boundary exchange of
data), especially in coastal regions, where small scale-phenomena are important, and
also increasing the spatial resolution for these regional/coastal systems to be able to
resolve smaller scales (so-called downscaling). Others have implemented coupling
with the atmosphere and/or sea ice. This paper provides a short review of these
operational GODAE systems.
