ILWS Uppsala, 12 june, 20077 TARANIS Dedicated to understanding Atmosphere/ionosphere/magnetosphere coupling (sprites, elves, blue jets…) Microcameras + photometer -MCM-CEA (+JP) EM measurements -IEM-LPCE (+PL,TCH) X-gamma Detector -XGD-LANL (USA), DNSC (DK) Detector of high Energy ElectronsCESR (+TCH) Quasi Sun Synchronous Orbit (2hrs LT drift/year) Phase B will start in september Launch expected for 2011

8. ILWS Uppsala, 12 june, 20078 TARANIS OBJECTIVES Description - characterization of the sprites and associated emissions, measurements of their occurrence frequency and of their distribution at the scale of the earth. (caméras, EM waves, X and  spectra, high energy electrons) - study of the effects of the magnetic latitude and volcanic activity Implied mechanisms - determination of the nature of the triggering phenomena (cosmic radiation) - determination of the source mechanisms (EM waves, X and  spectra, high energy electrons) - study of the nature of the explosive dissipation of energy in the ionosphere and magnetosphere (EM waves, X and  spectra, high energy electrons) Global impact - determination of the effects on the upper atmosphere, ionosphere and magnetosphere (EM waves, high energy electrons, associated ground based measurements, other satellites) - evaluation of the coupling atmosphere - ionosphere - magnetosphere and inter-planetary medium
