| 9 | NEMO_ (Nucleus for European Modelling of the Ocean) is a state-of-the-art modelling framework of |
|---|
| 10 | ocean related engines for oceanographic research, operational oceanography, seasonal forecast and |
|---|
| 11 | [paleo]climate studies. |
|---|
| 12 | |
|---|
| 13 | The NEMO ocean model has 3 major components: |
|---|
| 14 | |
|---|
| 15 | - :rstblue:`OPA` is fundamental to all users by modelling the ocean [thermo]dynamics and |
|---|
| 16 | solving the primitive equations; |
|---|
| 17 | - :rstgrey:`LIM` for sea-ice simulates ice [thermo]dynamics, brine inclusions and |
|---|
| 18 | subgrid-scale thickness variations; |
|---|
| 19 | - :rstgreen:`TOP-PISCES` models biogeochemistry with TOP for |
|---|
| 20 | the on/offline oceanic tracers transport and PISCES for the biogeochemical processes. |
|---|
| 21 | |
|---|
| 22 | These physical engines are described in their respective `reference publications`_. |
|---|
| 23 | |
|---|
| 24 | They are complemented by a 2-way nesting software (AGRIF_) and |
|---|
| 25 | a versatile data assimilation interface with 3 different modules |
|---|
| 26 | (linear-tangent TAM, observational operators OBS, and increment ASM). |

| 31 | |
|---|
| 32 | | Distributed under CeCILL license (GNU GPL compatible - see ``LICENSE``), |
|---|
| 33 | the framework offers several builtins reference configurations to |
|---|
| 34 | check your computing architecture and evaluate the model skills and performances (``./cfgs``). |
|---|
| 35 | | The end user could also find some idealized test cases on the web to serve as examples and |
|---|
| 36 | to study particular processes. |
|---|
| 37 | |
|---|
| 38 | A set of tools is also provided to setup your own configuration and |
|---|
| 39 | [pre|post]process your data (``./tools``). |

| 45 | For writing diagnostics in a efficient way, NEMO make use of XIOS_ server which |
|---|
| 46 | controlled the outputs using XML input file. |
|---|
| 47 | |
|---|
| 48 | To enable Earth system modelling, NEMO can be interfaced via |
|---|
| 49 | OASIS_ coupleur to external components such as atmospheric models or |
|---|
| 50 | alternative models of sea-ice or biogeochemistry. |

|---|
| 54 | ------------- |
|---|
| 55 | |
|---|
| 56 | The NEMO reference manual can be generated from the LaTeX source code (``./doc``), |
|---|
| 57 | either in PDF or in HTML format, but it mights require some additionnal installations. |
|---|
| 58 | |
|---|
| 59 | In any case, both formats are available online on the `NEMO website`__. |

| 65 | | The NEMO Consortium gathering 6 European institutes organises the sustainable development in order to |
|---|
| 66 | keep a reliable evolving system since 2008. |
|---|
| 67 | | It defined the multiyear development strategy which is implemented by the NEMO System Team. |
