Lefe (in French) (Fluid Envelopes and the Environment) is the major programme in the INSU's Ocean-Atmosphere field of research.
The major aim of the national and inter-agency Lefe programme is to encourage and support original, multidisciplinary and transversal research into how the atmosphere and the ocean function along with their coupling and interactions with the other components of the climate system. This means that one of the programme's main study subjects is the evolution of the Earth system under anthropogenic pressure. The Lefe programme works by supporting innovative or innovative projects combining observations, numerical simulations and advanced instrumentation developed in laboratories.
Coordinated and managed by the INSU, Lefe is supported by Ademe, CEA, CNES, CNRS (INSU, INC, INP, INSMI), IFREMER, INRIA, IRD, Météo-France, MTES and Mercator-Océan.
It is steered by a Scientific Council in conjunction with the Inter-Agency Committee made up of representatives from the partner organizations.
It works on 5 scientific project areas linked to the major international and European programmes:
- Atmospheric chemistry (Chat)
- Multiple interactions in the atmosphere, ice and the ocean (Imago)
- Biogeochemical cycles, the environment and resources (Cyber)
- Mathematical and digital methods (Manu)
- The Mercator Coriolis mission group (GMMC)
For several years now, the Lefe programme has provided an interface with the EC2CO programme.
