[P-EM27] Physics and Chemistry in the Atmosphere and Ionosphere

Tue. May 26, 2015 9:00 AM - 10:45 AM A01 (APA HOTEL&RESORT TOKYO BAY MAKUHARI)

Convener:*Yuichi Otsuka(Solar-Terrestrial Environment Laboratory, Nagoya University), Takuya Tsugawa(National Institute of Information and Communications Technology), Seiji Kawamura(National Institute of Information and Communications Technology), Chair:Yoshihiro Kakinami(School of Systems Engineering, Kochi University of Technology), Yoshihiro Tomikawa(National Institute of Polar Research)

This session covers a broad scope of studies of physics and chemistry in the atmosphere and the ionosphere. Coupling processes between plasma and neutral species, and upward and downward coupling among lower/upper atmosphere, and ionosphere/mesosphere/thermosphere including magnetosphere are discussed. We solicit papers based on experiments with ground-based and/or space-borne instruments, theoretical studies, numerical simulations, and development of new observation techniques.
