-This repository contains model settings ([code/](code/), [input/](input/)) and documentation ([readthedocs](http://eccov4.readthedocs.io/en/latest/)) that allow users to download, analyze, rerun, or modify ECCO version 4 ocean state estimates using the [MITgcm](http://mitgcm.org/) via on-premise cluster or via Amazon Web Services (see [example_scripts/](example_scripts/)). The master branch is based the ECCO version 4 release 2 solution (see below). If user support is needed, please contact <mitgcm-support@mit.edu> or <ecco-support@mit.edu>.

 **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.
