IUGONET project •The project aims to share upper atmospheric data that have been separately archived by various Japanese universities and institutes, and to accelerate research in the Solar-Terrestrial Physics (STP) field. •We have developed advanced tools, including a metadata database and analysis software, which facilitate data sharing and enable comprehensive data analysis.
