<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." /> |

<td rowspan="2"><p>ECCO was established in 1998 as part of the World Ocean Circulation Experiment (<A href="http://woce.nodc.noaa.gov/wdiu/">WOCE</A>) with the goal of combining a general circulation model (GCM) with diverse observations in order to produce a quantitative depiction of the time-evolving global ocean state. 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 /> |

It comes with a variety of packages including physical parameterizations, a sea-ice model, biochemical components, and allows flexible porting across various HPC platforms. <BR /> |

<td width="235" valign="top" bgcolor="#F3F2ED">Since the mid-1990's, groups at MIT, SIO, JPL and GFDL have applied automatic/algorithmic differentiation (AD) tools for generating tangent linear and adjoint code for ocean circulation and climate studies. ECCO relies heavily on the AD tool TAMC and its commecial successor TAF. The ECCO group is also involved in the development of a new open-source AD tool OpenAD. <BR /> |
