[P-EM20] Study of coupling processes in solar-terrestrial system

Wed. May 27, 2026 10:45 AM - 12:15 PM 304 (International Conference Hall, Makuhari Messe)

Chairperson:Yamamoto Mamoru(Research Institute for Sustainable Humanosphere, Kyoto University), Iwai Kazumasa(Institute for Space–Earth Environmental Research (ISEE), Nagoya University)

Solar-terrestrial physics is the research field that focuses on understanding the quantitative coupling processes between the Sun and Earth. The research area is vast, and combining multiple observation methods and modeling is essential. We have proposed a large-scale project called "Study of coupling processes in the solar-terrestrial system" to establish a comprehensive observation system from the solar wind to the Earth that includes the Equatorial MU radar, EISCAT_3D radar, a next-generation solar wind observation system, and a global observation network. This initiative will enable long-term monitoring of solar wind speed, magnetosphere variations in the polar regions, the vertical coupling of the atmosphere, and variations in the atmosphere/ionosphere at all latitudes. The IUGONET database enables integrated data handling and is widely used in this field. In this session, we solicit papers on solar-terrestrial physics and atmospheric science, namely, ground- and satellite-based observations, solar wind, space weather, models, and databases. By collaborating with participants from Japan and around the world, we will discuss trends and directions in solar-terrestrial physics and deepen consideration of future plans.
