[P-EM37_30PM1] Structure and Dynamics of the Magnetosphere

Wed. Apr 30, 2014 2:15 PM - 4:00 PM 414 (4F)

Convener:*Yoshizumi Miyoshi(Solar-Terrestrial Environement Laboratory, Nagoya University), Hiroshi Hasegawa(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Chair:Satoshi Kurita(Planetary Plasma and Atmospheric Research Center, Graduate School of Science, Tohoku University), Shigeto Watanabe(Department of Cosmosciences, Hokkaido University)

This session provides an opportunity to present recent results from satellite and ground-based observations, and theoretical and simulation studies, and discuss magnetospheric structures and phenomena including the solar wind-magnetosphere interaction, magnetosphere-ionosphere coupling, magnetic storms, and substorms. Discussion on planetary and satellite magnetospheres, future missions and instrument developments are also welcome.
