<h3>About NEMO</h3>

<a href="https://nemo-ocean.eu">NEMO</a> standing for <strong>Nucleus for European Modelling of the Ocean</strong> 
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.

<h4>Overview</h4>

<p>
The NEMO ocean model has 3 major components:
</p>

<ul style="list-style-type: disclosure-closed;">
   <li>
     <span style="color: blue;">NEMO-OCE</span> 
     models the ocean {thermo}dynamics and solves the primitive equations
   </li>
   <li>
     <span style="color: grey;">NEMO-ICE (SI<sup>3</sup>: Sea-Ice Integrated Initiative)</span> 
     models sea-ice {thermo}dynamics, brine inclusions and subgrid-scale thickness variations
   </li>
   <li>
     <span style="color: green;">NEMO-TOP (Tracers in the Ocean Paradigm)</span> 
     models the {on,off}line oceanic tracers transport and biogeochemical processes (using PISCES)
   </li>
</ul>

<p>
  These physical core engines are described in their respective 
  <a href="https://nemo-ocean.eu/documentation">reference manuals</a> 
  that must be cited for any work related to their use.
</p>

<h4>Additional capabilities</h4>

<ul style="list-style-type: square; padding-left: 1.5em;">
   <li>Create 
     <a href="https://nemo-ocean.eu/framework/components/interfaces/#Mesh_refinement_AGRIF">embedded zooms</a> 
     seamlessly thanks to 2-way nesting package <a href="https://agrif.imag.fr">AGRIF</a>
   </li>
   <li>Input-Output through effective 
     <a href="https://forge.ipsl.jussieu.fr/ioserver">XIOS</a> 
     software
   </li>
   <li>Coupling interface to other Earth system components based on 
     <a href="https://portal.enes.org/oasis">OASIS</a>
   </li>
   <li>Opportunity to integrate an external biogeochemistry model</li>
   <li>Versatile 
     <a href="https://nemo-ocean.eu/framework/components/interfaces/#Interfaces_with_observations">data interface</a>
   </li>
   <li>Set of 
     <a href="https://nemo-ocean.eu/framework/components/interfaces/">utilities</a> 
     is also provided to {pre,post}process your data
   </li>
</ul>

<h4>Reference Configurations and Test Cases</h4>

Several <a href="https://nemo-ocean.eu/framework/components/configurations">built-in configurations</a> are provided to evaluate the skills and performances of the model. 
They can be used as as first easy set-up and as template for setting up a new configuration.<br>
<a href="https://github.com/NEMO-ocean/NEMO-examples">Idealized test cases</a> addressing specific physical processes are also available for download.

<p>
Since 2014 the project has a <a href="https://www.geosci-model-dev.net/special_issue40.html">Special Issue</a> 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.<br>
Used by a wide audience, 
numerous <a href="https://nemo-ocean.eu/projects">associated projects</a> have been carried out and 
<a href="https://nemo-ocean.eu/bibliography/publications">various publications</a> are available.
</p>

<h4>Consortium bodies</h4>

<p>
The <a href="https://nemo-ocean.eu/category/institutes">NEMO Consortium</a> pulling together 5 European institutes 
plans <a href="https://nemo-ocean.eu/consortium/governance">the sustainable development</a> in order to 
keep a reliable evolving framework <a href="https://nemo-ocean.eu/consortium/history">since 2008</a>.

It defines the <a href="https://doi.org/10.5281/zenodo.1471663">multi-year development strategy</a> 
that is implemented by the <a href="https://nemo-ocean.eu/consortium/team">System Team</a> on a yearly basis 
in order to regularly release a new version.<br>
When the need arises, 
<a href="https://forge.ipsl.jussieu.fr/nemo/wiki/WorkingGroups">working groups</a> are created or resumed 
to gather the community expertise for advising on the development activities.
