[P-EM08] Progress in Physics of the Inner Magnetosphere

Tue. May 26, 2015 6:15 PM - 7:30 PM Convention Hall (2F)

Convener:*Danny Summers(Dept of Math and Stats,Memorial University of Newfoundland), Yusuke Ebihara(Research Institute for Sustainable Humanosphere, Kyoto University), Yoshizumi Miyoshi(Solar-Terrestrial Environement Laboratory, Nagoya University)

Earth's inner magnetosphere ,extending over magnetic shells L < 7, is a dynamic region of geospace comprising the radiation belts, the ring current, the plasmasphere, and the ionosphere. The Japanese mission ERG, planned for launch in 2016, will explore the inner magnetosphere and in particular will investigate particle energization in the outer radiation zone during space storms. ERG will be an exciting complement to existing space missions including the Van Allen Probes, THEMIS, Cluster, and small satellites such as CSSWE and Firebird. This session invites investigations of all aspects of inner magnetosphere physics including space and ground observations, modeling and simulations, and theory. Examples of topics of interest include particle energization and loss mechanisms, particle transport and injection, global modeling, energy coupling, generation and influence of geo-effective waves, wave-particle interactions, and diversity of inner magnetosphere responses to differing solar wind drivers.
