[PEM11-P22] New Space Weather Forecasting and Warning Types and Criteria Considering Social Impacts
キーワード：宇宙天気、衛星運用、通信・放送、航空被ばく
While many countries are studying the impact of space weather phenomena on social infrastructure and how to respond to them, the Ministry of Internal Affairs and Communications "Study Group on the Advancement of Space Weather Forecasting" has been held in Japan in 2022, and the report was released.(https://www.soumu.go.jp/menu_news/s-news/01tsushin05_02000047.html). Among the recommendations discussed in the study group, such as future observation, analysis, and forecasting related to space weather forecasting, and strengthening of the warning system, the formulation of new forecasting and warning standards that take into account the impact on social infrastructure and reliable warning distribution by the National Institute of Information and Communications Technology (NICT) is identified as particularly urgent issues.
The current NICT's forecasting and warning information focuses on the scale of the space weather phenomena and do not include information on social impacts, but forecasting and warning information based on social impacts are necessary for users to determine specific responses. Therefore,the Study Group examined new warning types and criteria that take into account the social impact of space weather phenomena, and established a total of 17 types of forecasts and warnings in the five fields of communications and broadcasting, positioning, satellite operations, electric power, and aviation exposure. For the fields of communications and broadcasting (HF band), space system operation (satellites), and aviation exposure for which thresholds have been established, we have studied the content and timing of warning distribution and developed an automatic distribution system. In this presentation, we provide an overview of the new warning types and criteria and NICT's recent efforts to advancement of space weather forecasting in Japan.
