ECCO version 4 release 2:

Estimating the Circulation and Climate of the Ocean version 4 release 2 is an ocean state estimate and solution of the MIT general circulation model that covers the period from 1992 to 2011 (Forget et al., 2016). It is a minor update of the original ECCO version 4 solution (Forget et al., 2015) that benefits from a few additional corrections listed in Forget et al. (2016) and is easier to analyze and re-run. Its input and output are distributed via the ECCO servers and permanently archived via the Harvard dataverse. They can be analyzed and manipulated using e.g. the gcmfaces and MITprof toolboxes.
