"Estimating the Circulation and Climate of the Ocean" (ECCO) is a data assimilating model that uses satellite and in situ data to make the best possible estimates of ocean circulation and its role in climate. Those solutions combine state-of-the-art ocean circulation models with global ocean datasets.
What sets ECCO apart from other models? ECCO reproduces observations in a physically and statistically consistent manner. ECCO provides information on sea level rise, sea ice loss, El Niño events, and the cycling of water and carbon.
ECCO's long-term goal is to produce global high-resolution coupled ocean/sea-ice/biochemical (and ultimately, atmosphere) state estimates to a wide community. ECCO's efforts toward this goal now include several projects, each of which is bringing ECCO closer to its long-term goal, while providing significant scientific contributions.
Additional information about ECCO can be found at their website https://ecco-group.org
The ECCO output hosted at PO.DAAC comes as a regularly spaced latitude-longitude grid by 0.5 degree available as a daily or monthly mean. These are suitable for users who have not used ECCO output previously and would like to use gridded ocean data. There are also the native cube sphere grid output, from which the 0.5 degree grids are derived. These are provided for those who are accustomed to using ECCO output.
The original ECCO output at 1 km spatial resolution on the native cube sphere grid can be found at https://data.nas.nasa.gov/ecco/. These are for expert users who are familiar with using ECCO output and can handle the petabyte data volume.
