宇宙天気観測や宇宙天気予報の国際的運用体制整備に関する論文が掲載されました
名古屋大学宇宙地球環境研究所融合研究戦略室では、宇宙天気研究の社会実装を目指した取組を積極的に進めています。具体的には、2025年度からの融合研究戦略課題公募のストラテジー型のテーマ課題として、「産学官連携による宇宙天気情報の社会実装」を追加し、宇宙天気現象という理学的アプローチと、社会インフラの応答という工学的アプローチ、および経済的なインパクトという分野横断的な研究を進めているところです。
この度、「Advances in Space Research」にて「Global Landscape of Space Weather Observations, Research and Operations」という論文が掲載されました。これは、宇宙天気観測や宇宙天気予報に関して、国内だけでなく、各国の運用体制の整備状況を網羅的に整理した論文です。
筆頭著者は、国立研究開発法人情報通信研究機構（NICT）で宇宙天気予報に従事されており、かつ、宇宙地球環境研究所融合研究戦略室の特任教授としても在籍されている石井 守先生です。

Abstract
The recognition of space weather hazards is increasingly growing, highlighting the importance of monitoring and forecasting it. High precision satellite positioning techniques have become essential in various areas of social and economic infrastructure. However, it is well-known that Global Navigation Satellite Systems (GNSS) can be affected by space weather-induced ionospheric variations. This poses a challenge as it can impact the reliability and accuracy of GNSS-based systems. Space weather phenomena can also have significant effects on aviation systems and electric power grids. Given that many of these phenomena occur on a global scale, it is crucial to have a comprehensive monitoring and observation network. Currently, numerous ground-based observations are managed by local government or academic bodies. In contrast, space-based observations are typically operated by space agencies, often necessitating international coordinated collaboration to undertake significant projects in this field. The paper puts a strong emphasis on the need for collaboration between various entities in each nation and between national programmes.
In this paper, the authors provide an overview of the international landscape for space weather research and operations at the nation-state level. They also highlight the activities of various national and regional space agencies involved in space weather research and monitoring for enhancing our capabilities in monitoring, forecasting, and mitigating the impacts of space weather phenomena on critical infrastructure and systems.
