|---|
| 13 | `NEMO <www.nemo-ocean.eu>`_ (Nucleus for European Modelling of the Ocean) is |
|---|
| 14 | a state-of-the-art modelling framework of ocean related engines for oceanographic research, |
|---|
| 15 | operational oceanography, seasonal forecast and [paleo]climate studies. |
|---|
| 16 | |
|---|
| 17 | The NEMO ocean model has 3 major components: |
|---|
| 18 | |
|---|
| 19 | - :rstblue:`OPA` is fundamental to all users by modelling the ocean [thermo]dynamics and |
|---|
| 20 | solving the primitive equations; |
|---|
| 21 | - :rstgrey:`LIM` for sea-ice simulates ice [thermo]dynamics, brine inclusions and |
|---|
| 22 | subgrid-scale thickness variations; |
|---|
| 23 | - :rstgreen:`TOP-PISCES` models biogeochemistry with TOP for the on/offline oceanic tracers transport and |
|---|
| 24 | PISCES for the biogeochemical processes. |
|---|
| 25 | |
|---|
| 26 | | These physical engines are described in their respective reference publications listed as BibTeX entries |
|---|
| 27 | in ``./REFERENCES.bib``. |
|---|
| 28 | | They are complemented by a 2-way nesting software (`AGRIF <http://agrif.imag.fr>`_) and |
|---|
| 29 | a versatile data assimilation interface with 3 different modules |
|---|
| 30 | (linear-tangent TAM, observational operators OBS, and increment ASM). |

| 35 | |
|---|
| 36 | | Shared under `CeCILL free software license <http://www.cecill.info>`_ (``./LICENSE.txt``), |
|---|
| 37 | the framework contains several builtins reference configurations and idealized test cases to serve as |
|---|
| 38 | examples and to study particular processes. |
|---|
| 39 | | A set of tools is also provided to setup your own configuration and [pre|post]process your data. |
|---|
| 40 | | |
|---|
| 41 | | For writing diagnostics in a efficient way, |
|---|
| 42 | NEMO requires `XIOS <http://forge.ipsl.jussieu.fr/ioserver>`_ as dependency |
|---|
| 43 | which controlled the outputs using XML input file. |
|---|
| 44 | | To enable Earth system modelling, NEMO can be interfaced via `OASIS <http://verc.enes.org/oasis>`_ to |
|---|
| 45 | interact with external components such as atmosphere models or |
|---|
| 46 | alternative models of sea-ice or biogeochemistry. |

| 52 | | The NEMO Consortium gathering 6 European institutes organises the sustainable development ( |
|---|
| 53 | ``./GOVERNANCE.rst``) in order to keep a reliable evolving system since 2008 (``./RELEASES.rst``). |
|---|
| 54 | | It defined the multiyear development strategy (``./ROADMAP.rst``) which is implemented by |
|---|
| 55 | the NEMO System Team (``./MAINTAINERS.rst``). |
