Electron temperature variation associated with the auroral energy input during the DELTA campaign
Abstract Japanese sounding rocket “S-310-35” was launched from Andøya Rocket Range in Norway on December 13, 2004 during Dynamics and Energetics of the Lower Thermosphere in Aurora (DELTA) campaign, in which the rocket-borne in-situ measurements and ground-based measurements were coordinated to cond...
