The Earth and the geo-space around it are always influenced by solar activity. In the division for integrated studies, we study the dynamics and structure of this "solar-terrestrial environment system" from the holistic aspect. Our study covers the various subjects from solar activities such as solar flares and sun-spots to geomagnetic phenomena such as aurora and magnetic storm. Collaborating with researchers with domestic and international partners, we are advancing the integrated study of data analyses from ground-based and space-born observations and the numerical simulation using high-performance computation.
Variations in the solar-terrestrial environment have various influences not only on satellites and astronauts but also on social infrastructure such as aviation, telecommunication and electric power grid. The long-term variation of solar activity may affect even the global climate. In the division for integrated study, we are also taking the research to advance the space weather forecast by predicting the solar-terrestrial environmental variation through scientific understanding in cooperation with relevant institutes.
We hope that many people are interested in the studies of our division.
