6 | NEMO for *Nucleus for European Modelling of the Ocean* is a state-of-the-art modelling framework of |
---|
7 | ocean related engines for oceanographic research, operational oceanography, seasonal forecast and |
---|
8 | [paleo]climate studies. |
---|
9 | |
---|
10 | Overview |
---|
11 | ======== |
---|
12 | |
---|
13 | Distributed under CeCILL license (GNU GPL compatible - see ``./LICENSE``), |
---|
14 | the NEMO ocean model has 3 major components: |
---|
15 | |
---|
16 | - :rstblue:`OPA` is fundamental to all users by modelling the ocean [thermo]dynamics and |
---|
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``). |
---|
22 | |
---|
23 | These physical engines are described in their respective reference publications that must be cited for |
---|
24 | any work related to their use. |

26 | Applications and capabilities |
---|
27 | ============================= |
---|
28 | |
---|
29 | Not only does the NEMO framework model the ocean circulation, |
---|
30 | it offers various features to enable |
---|
31 | |
---|
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) |
---|
36 | |
---|
37 | lation a efficient XIOS_ server for outputing diagnostics a coupled via OASIS_ to alternative components or other models to enable Earth system modelling. |
---|
38 | |
---|
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``). |
---|
43 | |
---|
44 | A set of tools is also provided to setup your own configuration and [pre|post]process your data (``./tools``). |
---|
45 | |
---|
46 | Literature |
---|
47 | ========== |
---|
48 | |
---|
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`_ |
---|
52 | |
---|
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. |
---|
59 | |
---|
60 | Community development |
---|
61 | ===================== |
---|
62 | |
---|
63 | | The NEMO Consortium gathering 6 European institutes organises the sustainable development in order to |
---|
64 | keep a reliable evolving system since 2008. |
---|
65 | | It defines the multi-year development strategy which is implemented by the NEMO System Team. |
---|
66 | |
---|
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. |
---|
