Meeting

2005 Joint Meeting for Earth and Planetary Science in Japan

Session description:: Japanese sounding rocket "S-310-35" was successfully launched on December 13, 2004 from Andøya rocket range in Norway. This rocket experiment aims at investigating the upper atmospheric dynamics and energetics accompanied with the auroral activity in the lower thermosphere. The instruments onboard success-fully made in-situ measurements of neutral temperature and density as well as auroral emission rate, electron density and temperature. Several ground-based observations substantial for such a discussion were simultaneously conducted in the vicinity of the launch site. In particular, the simultaneous measurement of neutral wind and temperature by ground-based Fabry-Perot Interferometer (FPI) and plasma density and temperature by EISCAT radar was a great success. This session is to summarize the onboard and the ground observations, followed by a related discussion as well as a comparison with theoretical modeling.

Convenors:: S. Nozawa (nozawa@stelab.nagoya-u.ac.jp); E. V. Thrane (eivind@rocketrange.no); T. Abe (abe@isas.jaxa.jp)
