Estimating the Circulation and Climate of the Ocean (ECCO)


ECCO logo

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).
ECCO-GODAE continues under NOPP sponsorship with support from the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA), and the National Oceanic and Atmospheric Administration (NOAA).

ECCO is a consortium formed by a group of scientists at the  Jet Propulsion Laboratory (JPL),    the Massachusetts Institute of Technology (MIT) and the Scripps Institution of Oceanography (SIO).

The consortium intends to bring ocean state estimation from its current experimental status to that of a practical and quasi operational tool for studying large-scale ocean dynamics, designing observational strategies, and examining the ocean's role in climate variability. See Report No.1. for a complete ECCO Science plan.

Our technical goal is the sustained production and evaluation of continuing three-dimensional estimates of the global state of the ocean in near-real time in support programs such as GODAE and CLIVAR. The main task is to bring together a global GCM with existing global data streams - including TOPEX/POSEIDON and JASON altimeter observations and in situ hydrographic and flow measurements such as what will be available from the ARGO program - to obtain the best possible estimate of the time evolving ocean circulation and related uncertainties.

Ongoing activities include a global WOCE-type synthesis and a prototype higher-resolution approach but with less constraints and thus quality.  Work progress and scientific achievements are reported in the  Project Reports Series and Publications.

Source code and  documentation of the ocean circulation model are provided in Model/Documentation. The setup and configuration
of  the model results and some animations are provided in Model Results/Animations.
Model outputs from the estimation activities are available from the ECCO project  Data Servers.

ECCO products are freely available through the project data servers. However,we ask that all users of the ECCO product use the following standard acknowledgment: "This is a contribution of the Consortium for Estimating the Circulation and Climate of the Ocean (ECCO) funded by the National Oceanographic Partnership Program."
