- NASA MARS 2020 rover :
Instrument Scientist on the proposed MARs Boundary Layer Lidar experiment (MARBLL) with PI Franck
- In 2010, Co-Principal Investigator of the Submillimeter Observations for Atmospheric Research (SOAR) to be
developed in the USA (JPL, M. Allen) and France. Proposed for the Exomars Trace Gas Orbiter and selected in payload B. Too expensive !
- In 2000-2002 : Principal Investigator of the "Mars Atmosphere Microwave Brightness Observer" (MAMBO), planned
to be the first microwave sounder around another planet (cancelled in phase B along with the Mars PREMIER mission).
My research is primarily focused on the development of Global Climate Models (GCM) designed to accurately simulate the environment
on other planets. The scientific applications are countless. On this basis, I am also deeply involved in space exploration, observations
analysis, and space instrumentation
- Modelling and theoretical studies on Extra-solar planets and their habitability
Development of a new kind of 3D Universal climate model aiming at simulating any terrestrial atmospheres with any given cocktail of
gases, clouds and aerosols, for any planetary size, and around any star. Applications :
- Study of the habitability of Proxima b and the environment on Trappist-1 worlds (with my student Martin Turbet)
- Demonstration that Gliese 581d is the first discovered terrestrial planet in the habitable zone (with post-doc R. Wordsworth)
- First 3D modelling of the runaway greenhouse phenomenon at the inner edge of the habitable zone (with postdoc J. Leconte).
- 3D simulations of the Early Earth Climate (Archean). Resolution of the faint young sun problem (with my student B. Charnay).
- And much more...
- Development of the first complete Pluto global climate model (including the methane cycle) and interpretation of the the NASA New
Horizons mission in 2015 (with my students T. Bertrand & M. Vangvichith, LMD)
- Explication of the distribution of glaciers and Pluto on Pluton with a Pluto thermal model able to run for 100,000 years
- Triton: Development of the first complete Global Climate Model of Triton, satellite of Neptune observed by Voyager 2
- Venus: Development of the first true General Circulation Model of the Venus atmosphere (project led by Sebastien
- Development of the LMD Mars Global Climate Model (GCM), used by several teams around the world.
- Analysis of Mars Spacecraft observations: ESA Mars Express, Current NASA Missions, Exomars Trace Gas orbiter, etc. (see above)
PI of the Mars Climate database
project supported by ESA -since 1995- and CNES -since 2001. This a reference
engineering and scientific tool used to prepare and analyse almost all missions to Mars.
The full version has been delivered to more than 300 teams in 23 different countries.
The database is also available on an
