Outline of Final Research Achievements

We aimed to elucidate the temporal and spatial structure of low-latitude ionosphere by utilizing the equatorial atmospheric radar (EAR), new satellite beacon observation, and whole-atmosphere general circulation model. We developed a new digital receiver and immediately received beacon radio waves that started transmitted in September 2020, and observed them stably after that. We analyzed the ionospheric structure at spatial scales of several hundred to several thousand km by EAR and satellite beacon observation, and analyzed the ionospheric structure using long-term EAR observation data. Regarding the elucidation of the mutual coupling of the ionosphere and the atmosphere using the simulation, the temperature and wind velocity in the low latitude stratosphere show a clear increase on the ESF activity day.

Academic Significance and Societal Importance of the Research Achievements

電離圏は地球の超高層大気(高度100~1000km)中の弱電離プラズマである。太陽起源の高エネルギー粒子による上からの変動と、下層の大気で生成される大気波動による下から変動にさらされ、複雑な振る舞いを示す。衛星が飛翔し地上との通信や測位の電波が通過する領域である電離圏の理解は、衛星の安定運用や衛星測位精度の確保に直結しており社会ニーズが高い。本研究では、下層大気の変動と赤道スプレッドF現象(ESF)の関連性についての証拠を得ることに成功した。これはESF日々変動解明進めるうえで重要な成果である。またインドネシアに位置する赤道大気レーダーによる長期連続観測を継続し貴重な観測データを集積した。
