Outline of Final Research Achievements

We investigated the propagation process of CME, which can have a serious impact on the environment around the earth. We developed a digital phased array system that enables us to observe the radio scattering phenomena (so called IPS) in eight directions simultaneously. We also developed a data assimilation system that includes the IPS data into the real-time MHD simulation. We found that the developed simulation system has higher accuracy than conventional prediction models.

Academic Significance and Societal Importance of the Research Achievements

CMEは地球周辺環境に擾乱をもたらし、通信障害や大規模停電など社会的な影響の大きい宇宙天気災害の原因となる。本研究ではその観測の高精度化を可能にするとともに、そのデータを取り込んだリアルタイム予測モデルを開発することで、高精度な予測を可能とした。本研究の成果は、宇宙天気の予報精度向上を通じて、今後ますます宇宙利用が進む社会の安定に貢献する。
