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." />

The importance of such an endeavor is recognized by numerous national and international organizations, such as the WMO's World Climate Research Programme (<A href="http://wcrp.wmo.int/">WCRP</A>) and UNESCO's Intergovernmental Oceanographic Comission (<A href="http://ioc.unesco.org/">IOC</A>). 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 products are in support of the Climate Variability and Predictability (<A href="http://www.clivar.org/">CLIVAR</A>) programme and the Global Ocean Data Assimilation Experiment (<A href="http://www.usgodae.org/">GODAE</A>).<br />

122 <p><strong><br />February 2014: Announcing a new-generation, global, bi-decadal state estimate: ECCO version 4</strong></p>
123 <p>Following the ECCO meeting in January at MIT, the JPL/MIT/AER ECCO-Production team is happy to announce the release of a new-generation, global, bi-decadal state estimate (ECCO-Production, release 1). The product covers the period 1992 to 2011.
124 <br>
125 <br>
126 Several aspects of this new product have been highlighted already during the ECCO meeting. To re-iterate, some of the features include a fully global grid (LLC90) with the inclusion of the Arctic Ocean, telescoping from 1 to 1/3 deg. in the tropics, a doubling in vertical resolution (from 23 to 50 levels), forcing with the ERA-Interim atmospheric reanalysis, and improved treatment of data sets in terms of resolved vs. unresolved scales. The state estimate is being made available on its native grid on the DODS/OPeNDAP server

130 <br>
131 <br>
132 The sub-directory ancillary_data/ has some extra information, including our standard analysis (standardAnalysis.pdf) that documents model-data misfits and physical variables of general interest. A copy of the matlab codes used to generate the standard analysis is also provided (gcmfaces_MITprof_r1.tar). As with releases of previous estimates, we think that many aspects of this release are mature (and improvements from previous versions), but with further improvements of some aspects to be expected in subsequent releases.
133 <br>
134 <br>
135 Gael Forget has played a leading role in developing ECCO v4 and producing the released estimate. A more detailed paper describing the design of ECCO v4, and the solution is in preparation for GMD:
