| Outline of Final Research Achievements |
This study aimed to elucidate the generation mechanism of medium-scase traveling ionospheric disturbances (MSTID) by coordinated sounding rockets and ground-based observations. On July 20, 2013, sounding rockets S-520-27 and S-310-42 were successfully launched from JAXA Uchinoura Space Center (USC). We simultaneously carried out observations from aircraft and gound sites. In association to MSTID, large horizontal variation in electron density and electric field were observed. Sporadic E layer was present at the same time. Including the behavior of the neutral wind, we successfully demonstrated that MSTID is generated in the situation expected from the model that was proposed before the experiment. Also at the same time, we successfully photographed resonance scattering from the Lithium cloud under the full-moon and midnight condition from the aircraft and the ground, which was the world first Li-release experiment by using the moonlight.
