AB: Taranis (Tool for the Analysis of RAdiations from lightNIngs and Sprites) is a CNES microsatellite project which will be in phase A in 2005. It proposes to measure sprites, halos, jets and elves and the associated terrestrial and X ray flashes, electromagnetic and electrostatic emissions, and energetic electrons at the nadir above thunderstorm. These complementary measurements will be carried on a local and global scale in order to understand the physical mechanisms responsible for the impulsive transfers of energy between the neutral atmosphere and plasmas of the ionosphere and magnetosphere. The purpose is to study the coupling between the low and middle atmosphere, the thermosphere, the ionosphere and the magnetosphere. The final goal is to establish the impact of these processes on the Earth's environment. The purpose of the presentation is to describe the project, its scientific objectives, the mission, the scientific payload. The sprite observation method at the nadir by spectral differentiation is already used by the experiment LSO (Lightning and Sprite Observations) on board of the International Space Station.
