概要

地球を取り巻く磁気圏・電離圏におけるプラズマ波動伝搬、波動粒子相互作用、高エネルギー粒子降下および放射線帯形成過程に関する地上および衛星観測・理論・シミュレーションの最新の研究成果について発表し議論した。

目的と具体的な内容

VERSIM (VLF/ELF Remote Sensing of the Ionosphere and Magnetosphere)国際共同研究作業部会は、国際電波科学連合(URSI)と国際地球電磁気学超高層物理学連合(IAGA)の連携の下にホイッスラー空電による磁気圏のリモートセンシング研究の作業部会が1975年に設立されたことに始まり、次第に研究領域も電離圏・磁気圏の電磁波動現象へと拡大されて、1989年にVERSIM作業部会と改名されて現在に至っている。最近では、2年毎に世界各地で研究集会が開催されてきており、その第9回目の研究集会が2020年3月に京都で開催されることになった。一方、ISEEでは、歴史的にもホイッスラー空電の研究が長く続けられてきたのみならず、現在も、地上のVLF電波観測網による磁気圏・電離圏観測および「あらせ」衛星による放射線帯の直接観測が活発に行われている。本研究集会では、京都大学生存圏研究所のスペース・プラズマ研究グループが名古屋大学宇宙地球環境研究所の地上・衛星観測の研究グループとも協力して、世界中から関連する研究者を集め、磁気圏・電離圏のプラズマ構造とその力学、波動粒子相互作用、波動波動相互作用の非線形過程、波動による高エネルギー粒子降下、磁気圏・電離圏の電磁波動伝搬等、VERSIM作業部会の研究テーマに関する最新の研究成果を発表し議論した。

生存圏科学の発展や関連コミュニティの形成への貢献

宇宙空間への拡大する人類の生存圏における電磁プラズマ環境について新たな知見を得るて、宇宙利用技術の開発・宇宙産業の発展に貢献するものである。
