:Release: |release| :Date: |today| `NEMO`_ for *Nucleus for European Modelling of the Ocean* is a state-of-the-art modelling framework, for research activities and forecasting services in ocean and climate sciences, developed in a sustainable way by a European consortium since 2008. .. contents:: :local: Overview ======== The NEMO ocean model has 3 major components: - |OPA| models the ocean [thermo]dynamics and solves the primitive equations (``./src/OCE``) :cite:`NEMO_manual`; - |SI3| simulates ice [thermo]dynamics, brine inclusions and subgrid-scale thickness variations (``./src/ICE``) :cite:`SI3_manual`; - |TOP| models the [on|off]line oceanic tracers transport and the biogeochemical processes (``./src/MBG``) :cite:`TOP_manual`. These physical core engines are described in their respective `reference publications`_, that must be cited for any work related to their use. Assets and ready-to-use solutions ================================= Not only does the NEMO framework model the ocean circulation, it offers various features to enable - Create :doc:`embedded zooms ` seamlessly thanks to 2-way nesting package `AGRIF`_. - Opportunity to integrate an :doc:`alternative biogeochemistry model ` - Versatile :doc:`data_assimilation `. - Generation of :doc:`diagnostics ` through effective `XIOS`_ server. - Roll-out Earth system modelling with :doc:`coupling interface ` to `OASIS`_. | Several :doc:`built-in configurations ` are provided to evaluate the skills and performances of the model which can be used as templates for :doc:`setting up a new configuration ` (``./cfgs``). | The end user could also find online some :doc:`idealised test cases ` to serve as templates and to study particular processes (``./tests``). A set of :doc:`utilities ` is also provided to [pre|post]process your data (``./tools``).

The main scope is to collect relevant manuscripts covering various topics and to provide a single portal to assess the model potential and evolution. Used by a wide audience, numerous :website:`associated projects ` have been carried out and extensive :website:`bibliography ` published. Collaborative development ========================= | The NEMO Consortium pulling together 5 European institutes (`CMCC`_, `CNRS`_, `MOI`_, `Met Office`_ and `NERC`_) plans the sustainable development in order to keep a reliable evolving framework since 2008. | It defines the |NEMO strategy|_ which is implemented by the System Team on a yearly basis in order to release a new version almost every four years. .. |NEMO strategy| replace:: multi-year development strategy When the need arises, :forge:`working groups ` are created or resumed to gather the community expertise for advising on the development activities. :doc:``
