<title>ECCO: Estimating the Circulation & Climate of the Ocean</title> |

<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."> |

              <p>The ECCO code is based on the <A href="http://mitgcm.org/" target="_blank">MIT general circulation model (MITgcm)</A>. It is freely available   for download through the <A href="http://mitgcm.org/source_code.html" target="_blank">MITgcm CVS repository</A>. The repository enables web-based access   to the model, and distributed code development. Code documentation is available   through the <A href="http://mitgcm.org/r2_web_testing/latest/online_documents/node1.html" target="_blank">online manual</A>. ECCO-specific configuration is documented in   chapter 8 of the manual. An <A href="http://mitgcm.org/mailman/listinfo/mitgcm-support" target="_blank">MITgcm   support and discussion group</A> has been set up where you can post your   questions or bug reports and browse previous Q's & A's.
