---|
[10460] | 3 | developed in a sustainable way by a European consortium since 2008. |

[10187] | 8 | Overview |
---|
| 9 | ======== |
---|
[9596] | 10 | |
---|
[10602] | 11 | The NEMO ocean model has 3 major components: |
---|
[10187] | 12 | |
---|
[11713] | 13 | - |OCE| models the ocean {thermo}dynamics and solves the primitive equations |
---|
| 14 | (:file:`./src/OCE`) |
---|
| 15 | - |ICE| simulates sea-ice {thermo}dynamics, brine inclusions and |
---|
| 16 | subgrid-scale thickness variations (:file:`./src/ICE`) |
---|
| 17 | - |MBG| models the {on,off}line oceanic tracers transport and biogeochemical processes |
---|
| 18 | (:file:`./src/TOP`) |
---|
[9596] | 19 | |
---|
[11708] | 20 | These physical core engines are described in |
---|
| 21 | their respective `reference publications <#project-documentation>`_ that |
---|
| 22 | must be cited for any work related to their use (see :doc:`citations`). |

[10602] | 24 | Assets and solutions |
---|
| 25 | ==================== |
---|
[9596] | 26 | |
---|
[10602] | 27 | Not only does the NEMO framework model the ocean circulation, |
---|
| 28 | it offers various features to enable |
---|
[9596] | 29 | |
---|
[10602] | 30 | - Create :doc:`embedded zooms<zooms>` seamlessly thanks to 2-way nesting package AGRIF_. |
---|
| 31 | - Opportunity to integrate an :doc:`external biogeochemistry model<tracers>` |
---|
| 32 | - Versatile :doc:`data assimilation<data_assimilation>` |
---|
| 33 | - Generation of :doc:`diagnostics<diagnostics>` through effective XIOS_ system |
---|
| 34 | - Roll-out Earth system modeling with :doc:`coupling interface<coupling>` based on OASIS_ |
---|
[9596] | 35 | |
---|
[10602] | 36 | Several :doc:`built-in configurations<configurations>` are provided to |
---|
| 37 | evaluate the skills and performances of the model which |
---|
[11713] | 38 | can be used as templates for setting up a new configurations (:file:`./cfgs`). |
---|
[9596] | 39 | |
---|
[10602] | 40 | The user can also checkout available :doc:`idealized test cases<test_cases>` that |
---|
[11713] | 41 | address specific physical processes (:file:`./tests`). |
---|
[9596] | 42 | |
---|
[11713] | 43 | A set of :doc:`utilities <tools>` is also provided to {pre,post}process your data (:file:`./tools`). |
---|

[10602] | 45 | Project documentation |
---|
| 46 | ===================== |
---|
[9596] | 47 | |
---|
[10602] | 48 | A walkthrough tutorial illustrates how to get code dependencies, compile and execute NEMO |
---|
[11713] | 49 | (:file:`./INSTALL.rst`). |
---|
[9596] | 50 | |
---|
[10602] | 51 | Reference manuals and quick start guide can be build from source and |
---|
[11713] | 52 | exported to HTML or PDF formats (:file:`./doc`) or |
---|
[11708] | 53 | downloaded directly from the :forge:`development platform<wiki/Documentations>`. |

---|
[10602] | 63 | Since 2014 the project has a `Special Issue`_ in the open-access journal |
---|
[11708] | 64 | Geoscientific Model Development (GMD) from the European Geosciences Union (EGU_). |
---|
[10602] | 65 | The main scope is to collect relevant manuscripts covering various topics and |
---|
| 66 | to provide a single portal to assess the model potential and evolution. |
---|
[10279] | 67 | |
---|
[10602] | 68 | Used by a wide audience, |
---|
| 69 | numerous :website:`associated projects<projects>` have been carried out and |
---|
| 70 | extensive :website:`bibliography<bibliography/publications>` published. |

| 73 | ================= |
---|
[10279] | 74 | |
---|
[11708] | 75 | The NEMO Consortium pulling together 5 European institutes |
---|
| 76 | (CMCC_, CNRS_, MOI_, `Met Office`_ and NERC_) plans the sustainable development in order to |
---|
| 77 | keep a reliable evolving framework since 2008. |
---|
[9596] | 78 | |
---|
[11708] | 79 | It defines the |DOI dev stgy|_ that is implemented by the System Team on a yearly basis |
---|
| 80 | in order to release a new version almost every four years. |
---|
[9596] | 81 | |
---|
[10602] | 82 | When the need arises, :forge:`working groups<wiki/WorkingGroups>` are created or resumed to |
---|
| 83 | gather the community expertise for advising on the development activities. |
---|
