The Eighth Symposium on Polar Science (4 – 8 December 2017)

Interdisciplinary Session
[IW] Whole atmosphere - including activities of JARE phase VIII and IX prioritized projects -
横断セッション [IW] 全大気圏 -南極地域観測第Ⅷ期・第Ⅸ期重点研究観測の活動を含めて-


Earth's lower, middle, and upper atmosphere interacts with one another through various kinds of vertical coupling processes induced by waves, physical and chemical processes, and energy input from the sun and magnetosphere. It compelled us to deal with the earth's atmosphere comprehensively, so that a new concept of "whole atmosphere" was recently introduced to the atmospheric research community. In the Antarctic, the first MST (Mesosphere-Stratosphere-Troposphere)/IS (Incoherent Scatter) radar has been operated since 2011 as a part of the JARE (Japanese Antarctic Research Expedition) phase VIII and IX prioritized projects. These projects aim at detecting climate change signals in each layer of the Antarctic atmosphere and exploring vertical coupling processes between these layers through the coordinated observations including the MST/IS radar in the Antarctic. These backgrounds stimulated us to propose this "whole atmosphere" session which extends and develops the previous "middle atmosphere and thermosphere" session. Viewpoints of both aeronomy and meteorology, and related interdisciplinary studies, are essential to understanding a wide altitude region from the troposphere to the thermosphere. This session provides an opportunity to present and discuss observational, theoretical, and modeling studies focusing on a variety of phenomena in each layer or across multiple layers of the earth's atmosphere.
This session will be held jointly with the PANSY workshop (H29 NIPR Symposium).

本セッションは平成29年度 国立極地研究所 研究集会「PANSY研究集会」との共催により開催されます。

Conveners : Kaoru Sato (U. Tokyo), Takuji Nakamura, Masaki Tsutsumi, Yoshihiro Tomikawa, and Toru Takahashi (NIPR)
