We study the near-Earth geospace with focus on the processes that affect the ionosphere within the Arctic region. Ionosphere is the ionized upper atmosphere between 70 and 1000 km altitude and it can be explored by instruments such as the international EISCAT radars and ESA’s Swarm satellites. Our aim is to understand how space weather events, such as solar wind high-speed streams and coronal mass ejections from the Sun affect the ionosphere. These events not only produce beautiful Northern lights, but also affect HF radio wave propagation and GNSS navigation.
Our research belongs to the university’s focus area “Earth and near-space system and environmental change”.
