95                <p class="headergray">NEWS</p>            <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.
96  <p><span class="headergray">Dec 2008: ECCO session at AGU Fall Meeting 2008</span></p>  <br>
97            <p> AGU's Fall Meeting 2008 will feature an ECCO session, identified as <a href="http://www.agu.org/meetings/fm08.old/index.php/Program/SessionSearch/?show=detail&sessid=45" target="_blank">OS04: CLIVAR/GODAE: The ECCO State Estimates</a>. This session will provide an opportunity for ECCO product users to (a) describe the scientific implications of their results, (b) enhance the feedback from the broader community to the Consortium, (c) foster the interaction between ECCO members and other scientists who utilize the state estimates. The <a href="http://www.agu.org/cgi-bin/sessions5?meeting=fm08&part=OS41F" target="_blank">oral part (OS41F)</a> will take place on <i>Thursday, Dec. 18th, starting 8am in MW Room 2022</i>.

98          <p><span class="headergray">Sep 2008: An eddy-permitting Southern Ocean State Estimate (SOSE)</span></p>  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
99            <p> As part of his Ph.D. thesis, <a href="http://www-pord.ucsd.edu/~mmazloff/" target="_blank">Matt Mazloff</a> has produced an eddy-permitting state estimate at 1/6 degree horizontal resolution of the Southern Ocean, covering the Argo-rich period 2005/06. The adjoint-based solution is dynamically consistent and enables closed budget calculations of various quantities. Matt's thesis was featured in the <a href="http://www.sdsc.edu/us/newsletter/common/newsletter.php?%20issue=2006-02&corner=fstory">SDSC Thread Newsletter</a>, and more recently in WHOI's Oceanus magazine (<a href="http://www.whoi.edu/oceanus/viewArticle.do?id=49240&archives=true" target="_blank">Corralling the Wild and Wooly Southern Ocean</a>).</p>  <br>

104                  The product is described in  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.
