TARANIS—a Satellite Project Dedicated to the Physics of TLEs and TGFs

Abstract : TARANIS (Tool for the Analysis of Radiations from lightNings and Sprites) is a CNES satellite project dedicated to the study of the impulsive transfer of energy between the Earth’s atmosphere and the space environment, and more precisely to the physics of Transient Luminous Events (TLEs) and Terrestrial Gamma‐ray Flashes (TGFs). The scientific background and the scientific payload have been described by Blanc et al. [1] and Lefeuvre et al. [2], respectively. The present note is an extended summary of paper 2, with a few updated information items.
