[P-EM16] Physics and Chemistry in the Atmosphere and Ionosphere

Tue. May 24, 2016 3:30 PM - 5:00 PM 106 (1F)

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:Shin-ichiro Oyama(Institute for Space-Earth Environmental Research, Nagoya University), Tatsuhiro Yokoyama(National Institute of Information and Communications Technology)

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.
