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.


The NEMO ocean model has 3 major components:

  • OCE models the ocean [thermo]dynamics and solves the primitive equations (./src/OCE)
  • SI3 simulates seaice [thermo]dynamics, brine inclusions and subgrid-scale thickness variations (./src/ICE)
  • TOP models the [on|off]line oceanic tracers transport and biogeochemical processes (./src/TOP)

These physical core engines are described in their respective reference documentation 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 embedded zoom seamlessly thanks to 2-way nesting package AGRIF.
  • Opportunity to integrate an external biogeochemistry model
  • Versatile data_assimilation (./src/OBS)
  • Generation of diagnostics through effective XIOS system
  • Roll-out Earth system modeling with coupling interface based on OASIS

Several 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 (./cfgs).

NEMO user can also checkout available idealized test cases that address specific physical processes(./tests).

A set of utilities is also provided to [pre|post]process your data (./tools).

Documentation and references

A walkthrough tutorial illustrates how to get code dependencies, compile and execute NEMO (./INSTALL.rst) .

Reference manuals and quick start guide can be build from source and exported to HTML or PDF formats (./doc) or downloaded directly from the NEMO website.

SI3 SI3 manual  
TOP TOP manual  

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 associated projects have been carried out and extensive bibliography published.

NEMO Consortium

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 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, working groups are created or resumed to gather the community expertise for advising on the development activities.
