Centre National de la Recherche Scientifique (CNRS-INSU)


The National Center for Scientific Research, or CNRS (Centre National de la Recherche Scientifique), is a public organization under the responsibility of the French Ministry of Education and Research.
Founded in 1939 by governmental decree, the CNRS aims to:

  • Evaluate and carry out all research capable of advancing knowledge and bringing social, cultural, and economic benefits for society.
  • Contribute to the promotion and application of research results.
  • Develop scientific information.
  • Support research training.
  • Participate in the analysis of the national and international scientific climate and its potential for evolution in order to develop a national policy.

With ten institutes that constitute the implementation of its science policy structures, the CNRS conducts research in all scientific, technological and societal fields. INSU (Institut National des Sciences de l’Univers , i.e. National Institute for Earth Sciences and Astronomy) is one of these ten CNRS institutes.


The National Institute for Earth Sciences and Astronomy aims to design, promote and coordinate national and international research in the fields of astronomy and of solid Earth, continental surfaces and interfaces, ocean, atmospheric and space sciences.

Working with other partner organizations and universities, the INSU carries out prospective scientific studies in order to identify emerging research areas that require priority support. As part of its joint programs, INSU funds research projects and sets up national and international facilities. INSU also helps to structure national research in its own field, in particular by managing the network of Observatoires des sciences de l’Univers (Earth Science and Astronomy Observatories-OSU).

The strategic priorities of INSU includes :

  • Climate change and variability, biogeochemical cycles (carbon cycle, nitrogen cycle, etc), atmosphere-cryosphere-ocean interaction, and atmospheric composition;
  • Interaction of continental surfaces and the Critical Zone with the atmosphere and oceans, evolution of eco-hydrological systems and their quality, and weather-related hazards.

The CNRS contribution to the NEMO Consortium is organised via INSU.


Ocean modelling with NEMO at CNRS is key to the scientific activity of about 200 students, researchers and engineers, including around 30 experts directly involved in developing and implementing new features in NEMO. Applications include both global configurations (with eORCA1, eORCA025, eORCA12,…) and regional configurations at higher resolution (in particular utilizing AGRIF capabilities).
