Research Abstract

By using EISCAT radars located in northern Scandinavia and Svalbard together with other radars (MF and meteor) as well as several optical instruments (sodium LIDAR, all-sky imagers, FPI, photometer, narrow TV imagers), we have conducted a wide range of research on the geospace. Over the four years from April 2010 to March 2014, we conducted more than 40 special experiments (SPs) for 865 hours. Part of SPs were made as international collaborative experiments with other associate countries. We have obtained new findings about several topics: Cowling channel, polar cap patch, vertical oscillation of the polar ionosphere, ion-neutral collision frequency, auroral heating, travelling ionospheric disturbances. We have published 57 scientific papers.
The EISCAT_3D radar is the next generation IS radar planed by the EISCAT community. We have discussed the EISCAT_3D project with Japanese colleagues as well as foreign colleagues, and have summarized a Japan's science plan using the EISCAT_3D.
