Global Aurora Dynamics Based on Polar Network Campaign

极光和磁场扰动观测活动和观测网络已在极地地区开展和部署，主要是加拿大，部分延伸到格陵兰、斯匹次卑尔根和挪威，特别侧重于与磁层过程有关的全球性质和动态。通过1991年和1992年夏季的两次实地工作，在17个地点建立了磁力计网络，其中包括磁通门-感应磁力计组合系统，在8个地点建立了感应磁力计网络。在产生重要和令人感兴趣的数据的磁力仪站点中，尤里卡的特殊之处在于其位置接近地磁北极一度。1992年12月和1993年1月，我们在极冠、极裂和极光带设置了7台超高灵敏度电视摄象机，以高时间分辨率记录了全球极光图象的动态特征。极光活动与萨斯喀彻温大学在四个地点进行的另一个类似电视系统的活动以及NRC的极光和磁场CANOPUS计划相协调。三颗卫星，Geotail，Akebono和Freja，是进行联合研究的好位置，有可能在电视摄像机网络的视野范围内的磁力线足迹处被捕获。

Campaign and network observations for aurora and magnetic field disturbances were carried out and deployed in the polar region, mainly Canada with some extension to Greenland, Spitzbergen and Norway, specifically focused to the global nature and dynamics linked with the magnetospheric processes. The magnetometer network was established at 17 sites with a combined system of fluxgate-induction magnetometers and at 8 site with an induction magnetometer through twice of field work in the summer of 1991 and 1992. Among the magnetometer sites producing important and interesting data, Eureka is specialized by its location close within one degree to the geomagnetic north pole. In December 1992 and January 1993 seven ultra-high sensitive TV cameras were set in the polar cap, cleft and auroral zone to recorded dynamic features of global auroral pattern in high time resolution. The auroral campaign was coordinated with the another campaign with similar TV systems at four sites conducted by University of Saskatchewan and with CANOPUS program of aurora and magnetic field by NRC. Three satellites, Geotail, Akebono and Freja, Were good location for conjunction study with possibilities to be caught at the foot prints of magnetic lines of force within the range of field of view of the TV camera nework.
