[10187] | 6 | NEMO for *Nucleus for European Modelling of the Ocean* is a state-of-the-art modelling framework of |
---|
[9596] | 7 | ocean related engines for oceanographic research, operational oceanography, seasonal forecast and |
---|
| 8 | [paleo]climate studies. |

[10187] | 10 | Overview |
---|
| 11 | ======== |
---|
[9596] | 12 | |
---|
[10187] | 13 | Distributed under CeCILL license (GNU GPL compatible - see ``./LICENSE``), |
---|
| 14 | the NEMO ocean model has 3 major components: |
---|
| 15 | |
---|
[9596] | 16 | - :rstblue:`OPA` is fundamental to all users by modelling the ocean [thermo]dynamics and |
---|
[10187] | 17 | solving the primitive equations (``./src/OCE``); |
---|
| 18 | - :rstgrey:`SI`\ :rstgreysup:`3` for sea-ice simulates ice [thermo]dynamics, brine inclusions and |
---|
| 19 | subgrid-scale thickness variations (``./src/ICE``); |
---|
| 20 | - :rstgreen:`TOP-PISCES` models biogeochemistry with TOP for the on/offline oceanic tracers transport and |
---|
| 21 | PISCES for the biogeochemical processes (``./src/MBG``). |
---|
[9596] | 22 | |
---|
[10187] | 23 | These physical engines are described in their respective reference publications that must be cited for |
---|
| 24 | any work related to their use. |

[10187] | 26 | Applications and capabilities |
---|
| 27 | ============================= |
---|
[9596] | 28 | |
---|
[10187] | 29 | Not only does the NEMO framework model the ocean circulation, |
---|
| 30 | it offers various features to enable |
---|
[9596] | 31 | |
---|
[10187] | 32 | - 2-way nesting package `AGRIF`_ to create embedded zooms seamlessly |
---|
| 33 | - Flexible biogeomchemistry with online coarsening and possible integration of a customized model |
---|
| 34 | - Versatile data assimilation interface with 3 different modules |
---|
| 35 | (tangent linear, observational operators and increments) |
---|
[9596] | 36 | |
---|
[10187] | 37 | lation a efficient XIOS_ server for outputing diagnostics a coupled via OASIS_ to alternative components or other models to enable Earth system modelling. |
---|
[9596] | 38 | |
---|
[10187] | 39 | | Several builtins configurations are provided to assess the skills and performances of the model which |
---|
| 40 | can be used as templates for setting up a new configuration (``./cfgs``). |
---|
| 41 | | The end user could also find some idealised test cases on the web to serve as examples and |
---|
| 42 | to study particular processes (``./tests``). |
---|
[9596] | 43 | |
---|
[10187] | 44 | A set of tools is also provided to setup your own configuration and [pre|post]process your data (``./tools``). |
---|
[9596] | 45 | |
---|
[10187] | 46 | Literature |
---|
| 47 | ========== |
---|
[9596] | 48 | |
---|
[10187] | 49 | | The NEMO reference manual and a quick start guide can be generated from Latex and RST source code files |
---|
| 50 | (``./doc``), either in PDF or in HTML format, but it might require some additional installations. |
---|
| 51 | | In any case, both formats are available online: `HTML`_ | `PDF`_ |
---|
[9596] | 52 | |
---|
[10187] | 53 | | Since 2014 the project has a `Special Issue`_ in the Geoscientific Model Development (GMD) open-access journal |
---|
| 54 | from the European Geosciences Union (EGU). |
---|
| 55 | The main scope is to collect relevant manuscripts which cover a wide variety of topics like |
---|
| 56 | process studies, new parameterizations, implementation of new model features and new NEMO configurations. |
---|
| 57 | | Also it provides a single portal to search, discover and understand about |
---|
| 58 | the NEMO modelling framework potential and evolution and to submit their contributions. |
---|
[9596] | 59 | |
---|
| 60 | Community development |
---|
[10187] | 61 | ===================== |
---|
[9596] | 62 | |
---|
| 63 | | The NEMO Consortium gathering 6 European institutes organises the sustainable development in order to |
---|
[10187] | 64 | keep a reliable evolving system since 2008. |
---|
| 65 | | It defines the multi-year development strategy which is implemented by the NEMO System Team. |
---|
[9596] | 66 | |
---|
[10187] | 67 | `Working groups`_ are regularly created or resumed to gather the expertise in the NEMO community in order to |
---|
| 68 | focus the development work on a specific subject or major component of NEMO. |
