Ground-Satellite observation of geospace environment over Siberia and Japan

2007-2008年间，我们在俄罗斯远东地区的马加丹和帕拉通卡安装了全天冷却的ccd成像仪和感应磁力计。通过将现有的成像仪与SuperDARN北海道雷达和日本新安装的感应磁力仪相结合，我们开发了一个纬向地面站链来观测高层大气和地球空间。利用这些地面观测和卫星观测，我们研究了风暴期间的宽带电子降水，它可以引起低纬红色极光，以及亚极光到中纬度地区的电离层扰动。

We installed all-sky cooled-CCD imagers and induction magnetometers at Magadan and Paratunka in Far-East Russia in 2007-2008. By combining pre-existing imagers and the SuperDARN Hokkaido radar and newly-installed induction magnetometers in Japan, we developed a latitudinal chain of ground-based stations to observe the upper atmosphere and geospace. Using these ground-based observations as well as satellite observations, we investigate storm-time broadband electron precipitation, which can cause low-latitude red auroras, and ionospheric disturbances in the subauroral region to middle latitudes.
