[P-EM10] Space Weather and Space Climate

Wed. May 28, 2025 1:45 PM - 3:15 PM 301B (International Conference Hall, Makuhari Messe)

convener:Ryuho Kataoka(National Institute of Polar Research), Antti Pulkkinen(NASA Goddard Space Flight Center), Mary Aronne(NASA GSFC/CUA), Yumi Bamba(National Institute of Information and Communications Technology), Chairperson:Ryuho Kataoka(National Institute of Polar Research), Yumi Bamba(National Institute of Information and Communications Technology)

We share the latest scientific papers to understand how the space environment changes in various time scales and to discuss how we will react via international and interdisciplinary collaborations. More specifically, welcomed papers include space climate studies to reconstruct the long-term variations; cutting-edge observational and modeling studies of space weather from the Sun to surface of the Earth; applied science such as operational space weather forecast using machine-learning techniques and hazard assessments for deep space human spaceflight activities at Moon and at Mars.
