Understanding the linkage among the Sun, geospace and Earth’s atmosphere

Earth's atmosphere and geospace studied in this project, with a picture of the EISCAT Svalbard Radar
This project aims to clarify the coupling processes among the Sun, geospace and Earth's atmosphere in polar regions. To achieve this objectives, we are strengthening national and international collaborative studies with facilities in both polar regions; Antarctic atmospheric radar (PANSY) at Syowa Station; European Incoherent Scatter (EISCAT) radars in northern Scandinavia and Svalbard; SuperDARN HF radar network, and ; Ground-based networks of optical imagers and magnetometers. We are also developing new observation systems such as optical imagers, lidars, and the next-generation geospace/atmospheric radar called ‘EISCAT_3D’. Based on these ground-based remote-sensing together with satellite observations and theoretical/ simulation studies, we will pursue quantitative understanding and future prediction of the coupling processes among the Sun, geospace and Earth's atmosphere.
