NEMO (Nucleus for European Modelling of the Ocean) is a state-of-the-art modelling framework of ocean related engines for oceanographic research, operational oceanography, seasonal forecast and [paleo]climate studies.
The general description of the model and its components, the governance of its developments, the NEMO Consortium… is available on the NEMO official public web site: ​www.nemo-ocean.eu

Here you'll find how to download and install the NEMO reference code, to build our reference configurations, to find information, documentation, so as all the tools to interact with the NEMO community.
