second Pilot Project arose in a somewhat unexpected area, sea surface
temperature; a field that the community had believed was being estimated
well. The GODAE High-Resolution SST Pilot Project (see chapter by I.
Robinson in this volume) aims to deliver integrated, high-resolution
products, derived from a range of different, but complementary observing
systems, that properly respect our understanding of the near-surface
temperature structure (e.g., the skin effect) and addresses issues such as the
diurnal cycle.
Various data servers will be responsible for maintaining and monitoring
the data flow to assimilation groups and to those undertaking
validation/evaluations. The GODAE Monterey server and the CORIOLIS
Centre (see chapter by S. Pouliquen in this volume) are two examples of this
important functionality. One of the tasks is to link the server functions
together so that the data users will have a consistent and transparent interface
to the variety of data that are available. One of the challenges facing
GODAE (and others) is the establishment of adequate metadata to facilitate
data tracking, intercomparisons, and distribution of data which may undergo
revision through various quality control procedures.
Perspective #3:
The real impact of GODAE will
come through its ability to bring its complex data and
information to applications and users.
5.2
Models and data assimilation
Because of the irregular and incomplete nature of the datasets relative to
the scales of interest, a considerable burden in ocean state estimation and
forecasting is placed not only on the assimilation components but also on the
model. The model provides a capacity to extrapolate information, enabling
past data to be used for present analyses, and present data to be used as a
basis for predictions of the ocean state at future times (forecasts). Other
papers in this Volume discuss approaches to modeling and data assimilation
and some of the issues faced by the GODAE community.
Most of the target applications require good representation of, at least,
temperature and velocity components and sea level. High resolution
operational oceanography requires accurate depiction of mesoscale ocean
features such as eddies and the meandering of currents and fronts and of
upper ocean structure. Coastal applications require accurate sea level and
cross-shelf transport estimates. Seasonal-to-interannual climate forecasts
require a good representation of the upper ocean temperature and salinity
fields. Decadal climate monitoring and research requires attention to the
thermohaline circulation, among other things. Biogeochemical applications
