.. todo:: 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: - |OCE| models the ocean {thermo}dynamics and solves the primitive equations (:file:`./src/OCE`) - |ICE| simulates sea-ice {thermo}dynamics, brine inclusions and subgrid-scale thickness variations (:file:`./src/ICE`) - |MBG| models the {on,off}line oceanic tracers transport and biogeochemical processes (:file:`./src/TOP`) These physical core engines are described in their respective `reference publications <#project-documentation>`_ that must be cited for any work related to their use (see :doc:`cite`). Assets and 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:`external biogeochemistry model` - Versatile :doc:`data assimilation` - Generation of :doc:`diagnostics` through effective XIOS_ system - Roll-out Earth system modeling with :doc:`coupling interface` based on OASIS_ Several :doc:`built-in configurations` are provided to evaluate the skills and performances of the model which can be used as templates for setting up a new configurations (:file:`./cfgs`). The user can also checkout available :doc:`idealized test cases` that address specific physical processes (:file:`./tests`). A set of :doc:`utilities ` is also provided to {pre,post}process your data (:file:`./tools`). Project documentation ===================== A walkthrough tutorial illustrates how to get code dependencies, compile and execute NEMO (:file:`./INSTALL.rst`). Reference manuals and quick start guide can be build from source and exported to HTML or PDF formats (:file:`./doc`) or downloaded directly from the :forge:`development platform`. ============ ================== =================== Component Reference Manual Quick Start Guide ============ ================== =================== |NEMO-OCE| |DOI man OCE|_ |DOI qsg| |NEMO-ICE| |DOI man ICE| |NEMO-MBG| |DOI man MBG| ============ ================== =================== Since 2014 the project has a `Special Issue`_ in the open-access journal Geoscientific Model Development (GMD) from the European Geosciences Union (EGU_). 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. Development board ================= 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 |DOI dev stgy|_ that is implemented by the System Team on a yearly basis in order to release a new version almost every four years. When the need arises, :forge:`working groups` are created or resumed to gather the community expertise for advising on the development activities. .. |DOI dev stgy| replace:: multi-year development strategy Disclaimer ========== The NEMO source code is freely available and distributed under :download:`CeCILL v2.0 license <../../../LICENSE>` (GNU GPL compatible).
