ESTIMATING THE CIRCULATION
AND CLIMATE OF THE OCEAN (ECCO)
ECCO was established in 1999 as part of the World Ocean Circulation
with the goal of combining a general circulation model (GCM) with diverse
observations in order to produce a quantitative depiction of the time-evolving
global ocean state. The importance of such an endeavor is recognized
by numerous national and international organizations, such as the WMO's
World Climate Research Programme (WCRP)
(and within it the Climate Variability and Predictability, CLIVAR) programme),
UNESCO's Intergovernmental Oceanographic Commission (IOC)
(and within it the Global Ocean Data Assimilation Experiment project, GODAE).
These programs have all noted the necessity of synthesizing the diverse
remotely-sensed and in-situ observations with known dynamics and thermodynamics
through a GCM.
ECCO was initially formed under the National Ocean Partnership Program
(NOPP) with funding provided by the National Science Foundation (NSF),
the National Aeronautics and Space Administration (NASA), and the Office
of Naval Research (ONR). Funding now also comes from directly from NASA
and the National Oceanic and Atmospheric Administration (NOAA).
The long term goal of ECCO is to provide a high resolution coupled
ocean/sea-ice/biochemical (and ultimately consistent atmospheric)
state estimate to a wide community. In contrast to so-called
numerical weather prediction, these estimates will include the ocean's
history as well as predictions. ECCO's efforts toward this goal now
include several projects, each of which is bringing ECCO closer to its
long term goal, while providing significant scientific contributions.
These projects include efforts at ECCO-SIO, ECCO-JPL,
