Electron temperature variation associated with the auroral energy input during the DELTA campaign

摘要: Japanese sounding rocket “S-310-35” was launched from Andoya Rocket Range in Norway on December 13, 2004 during Dynamics and Energetics of the Lower Thermosphere Aurora (DELTA) campaign, which rocket-borne in-situ measurements ground-based were coordinated to conduct a comprehensive observation upper atmospheric response against auroral energy input. The Fast Langmuir Probe (FLP) installed study thermal structure balance plasma by measuring electron temperature polar lower ionosphere. FLP observations indicate that temperatures found be remarkably high an altitude range 106 km 114 ascending phase rocket. lowest part this region might affected artificial beam generated N2 instrument same On other hand, small increase observed at 119 descending phase. This is possibly first time both density fluctuation may caused Farley-Buneman instability detected observation.
