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.

通过使用位于斯堪的纳维亚半岛北方和斯瓦尔巴群岛的EISCAT雷达以及其他雷达（MF和流星）以及几种光学仪器（钠激光雷达，全天空成像仪，FPI，光度计，窄电视成像仪），我们对地球空间进行了广泛的研究。从2010年4月到2014年3月的四年时间里，我们进行了40多项特殊实验（SP），时间长达865小时。部分战略计划是作为与其他联系国的国际合作试验而制定的。我们获得了一些新的发现：Cowling通道，极冠斑块，极地电离层的垂直振荡，离子中性碰撞频率，极光加热，电离层扰动。EISCAT_3D雷达是EISCAT团体计划的下一代IS雷达。我们与日本同行以及外国同行讨论了EISCAT_3D项目，并总结了日本使用EISCAT_3D的科学计划。
