NEMO (Nucleus for European Modeling of the Ocean) is a state-of-the-art modeling
framework used in oceanographic research, climate and seasonal forecast and operational
The current release of NEMO includes three engines (or components):
- OPA9 : the dynamical part of the ocean component.
- LIM2 : the sea-ice component .
- TOP1 : a transport component based on OPA9 tracer advection-diffusion equation (TRP)
    and a biogeochemistry model which include two components: LOBSTER and PISCES
Theses ocean related components of the earth system can work together or separately. This
framework is intended to be interfaced with the remaining component of the earth system
(atmosphere, land surfaces, ...) via the OASIS coupler.
NEMO is distributed under CeCILL license (version 2). In order to define and organize
human expertise and financial resources, the major partners (CNRS, MERCATOR-OCEAN,
UK-Met. Office and NERC/NOCS) will be organized within the NEMO Consortium.

NEMO is widely used in Europe (mainly France, UK and Italy) and Canada but also in US,
Japan and China... It represents a community of more than 300 users organized around ~80
projects. Studies involving NEMO explore a very large diversity of problems with temporal
scales ranging from hours to thousand of years, spatial scales ranging from meter to global
scale and configurations ranging from academic square boxes to global earth system
modeling. NEMO is present in major European scientific projects (DRAKKAR,
DYNAMITE, ENSEMBLES, CARBOCEAN). It is coupled to most of European atmospheric
models (Arpege, LMDz, Hadley Family, ECHAM, IFS, CLM) and was used in IPCC
experiments (IPSL and Meteo-France) and for seasonal forecast (ECMWF, Meteo-France,
Morocco, Tunisia, EC-Earth). NEMO is also the engine used in operational oceanography by
MERCATOR-OCEAN, Department of Fisheries (Canada), Hadley Center and UK-Met.
