PERSPECTIVES FROM GODAE
7
Regular depictions of the ocean state will be obtained through synthesis
of observations with ocean model estimates. The models will allow us to
assimilate and integrate complex information in a way that is consistent with
our knowledge of ocean dynamics and physics.
Scientifically, in the totality of its complexity, the problem is enormous.
Yet, it is evident that most aspects are now tractable. The benefits of
assimilation of ocean observations into ocean and climate models has been
demonstrated (e.g., Ji et al., 1998; Giraud et al., 1997; Burnett et al., 2002, and
papers within that Volume; Wunsch, 2001). A system of ocean data
collection and modeling of the ocean that will allow us to follow the state of
the ocean routinely seems in the realm of feasibility (see also Smith and
Lefebvre, 1997).
4.2
The rationale
GODAE is inspired by both opportunity and need. There is a genuine
user demand for ocean products, for a range of time and space scales (e.g.,
Flemming 2001, Altalo, this Volume). There is also a concern for future
ocean research. A capability for providing regular ocean analyses is required
as a framework for scientific research and development. In addition, if we
are to build a future with a robust, routine, permanent and well-supported
network of ocean observations, then a clear and convincing demonstration of
the feasibility, practicality and value of maintaining such a network is
required.
The opportunities arise because of the development and maturity of
remote and direct observing systems, making global real-time observation
feasible; the steady advances in scientific knowledge and our ability to
model the global ocean and assimilate data at fine space and time scales; the
genuine enthusiasm of the ocean community to promote and implement
integrated global observing systems; and the critical advances provided by
research programs (see Section 2).
The underlying rationale for the organization of this activity as an
international experiment is that achieving the GODAE vision will not
happen serendipitously and that the needed capacity will not be realized
without a concerted effort to ensure, first, proper integration of the
components and, second, the commitment to proving value and viability.
4.3
The approach
Smith (2000) and IGST (2000) introduce the objectives and scope of
GODAE and the reader is referred to those publications and the GODAE
web site for details.
