5     <meta name="description" content="Welcome to the Estimation of the
6     Circulation and Climate of the Ocean (ECCO) project homepage. ECCO is a consortium
7     involving the Massachusetts Institute of Technology (MIT), the Jet Propulsion
8     Laboratory (JPL/NASA), the Scripps Institution of Oceanography (SIO/SDSC) and the Institut
9     fuer Meereskunde at the University of Hamburg (IfM). It is funded by the National
10     Oceanographic Partnership Program (NOPP). The long term goal of ECCO is to provide
11     a high resolution coupled ocean/sea-ice/biochemical (and ultimately, consistent
12     atmospheric) state estimate to a wide community." />

91     <p><strong>Brief introduction </strong></p>
92     <p>ECCO products are freely available through several applications. However, we ask that all users of these product use the following standard acknowledgment: "The state estimates were provided by the ECCO Consortium for Estimating the Circulation and Climate of the Ocean funded by the National Oceanographic Partnership Program (NOPP)." <BR />
93     <BR />
94     Data servers contain four groups of data: </p>
95     <UL>
96     <LI>Monthly, 10-day, daily or 12-hourly ocean model state, adjusted forcing fields and mixing coefficients
97     </li><LI>Obsevational data sets as they enter the optimization
98     </li><LI>Misfits between model output and available observations, as computed by the model cost/objective function
99     </li><LI>Past published estimates are also kept on the data servers </LI>
100     </UL>
