Sandrine Guerlet

Researcher in Planetary sciences

Research interests

My research work focuses on the remote sensing of planetary atmospheres. I am particularly interested in the study of atmospheric composition, thermal structure, radiative balance, dynamics and climate of various planetary atmospheres. To achieve these goals, I acquired expertise in the analysis of infrared spectroscopic data, the development of radiative transfer models and retrieval algorithms.

Current position & Projects

Since October 2014, I am a CNRS researcher at the Laboratoire de Météorologie Dynamique (LMD). My research activities focus on the study of Saturn's and Jupiter's atmospheres, both from remote sensing (Cassini/CIRS, ground-based observations) and via the development of a new General Circulation Model (GCM), in collaboration with other LMD researchers.

Since 2016, I am also involved in the ExoMars Trace Gas Orbiter mission. I analyse thermal infrared spactra acquired by the ACS instrument to map the tropospheric temperature of the Martian atmosphere as well as the dust and water ice integrated optical depth, at various local times. These results are then exploited in a data assimilation scheme coupled to the LMD Mars GCM.
