在诺里尔斯克观测的高纬度电离层的不均匀结构
Inhomogeneous structure of the high-latitude ionosphere as observed at Norilsk
摘要：
1995年3月和8月/9月、1996年2月和1998年3月至4月，在诺里尔斯克对高纬度电离层的不均匀结构进行了观测（地磁纬度和经度分别为北纬64.2度和东经160.4度，L=5.2）。在不同的地球物理条件下，研究了电离层F层的小尺度不规则体（寿命为几秒，空间尺度小于5-7 km）和中等尺度波动不规则体（周期为10-50 min，水平尺度为几十和几百km）。总共记录了300小时的观测，包括来自F2层的250次反射，以及来自零星E层的其他反射。得到了3月和4月非均匀结构参数的日变化。介绍了电离层不规则性参数与地磁活动的关系。
英文摘要：
In March and August/September 1995, February 1996, and in March-April 1998, observations of the inhomogeneous structure of the high-latitude ionosphere were carried out at Norilsk (geomagnetic latitude and longitude are 64.2 N and 160.4 E, and L=5.2). Small-scale irregularities (with the lifetime of several seconds,and the spatial scale less than 5-7 km), and medium-size wave irregularities(with the period of 10-50 min, and the horizontal size of tens and hundreds of kilometres) of the ionospheric F layer were investigated under different geophysical conditions. A total of 300 hours of observations was recorded, including 250 reflections from the F2 layer, and the other reflections from the sporadic E layer. The diurnal variations of inhomogeneous structure parameters in March and April is obtained. Dependence of some ionospheric irregularity parameters on geomagnetic activity is presented.
