Abstract

Numerical values of the criteria for the efficiency of the determination of the critical frequency of the F2 layer of ionosphere over European Russia are calculated with ionospheric models corrected based on vertical-incidence sounding data from an ionosonde. Two correction techniques are considered: the selection of an effective value of the input heliogeophysical index and linear-correlation correction of ionospheric models with respect to the critical frequency of the F2 layer of the ionosphere. Domains in which model correction by one point is effective are found. They determine the current coverage of the European Russia by the Russian ionospheric observation network. The regions in which the correction of median models is noticeable in comparison with the median models without correction are shown to be 7° in latitude and 15° in longitude at the midlatitudes. It is ascertained that it is mainly impossible to determine the ionospheric parameters at northern points and points in the region of the main ionospheric trough via correction based on data from midlatitude ionospheric observation sites. In these cases, the climate models without correction are more effective.

在低黑子活动期间通过离子探空仪的垂直入射测深数据对电离层模型进行校正的效率

摘要

确定电离层F 2层临界频率的效率标准的数值是根据基于电离探空仪的垂直入射测深数据校正的电离层模型计算得出的。考虑了两种校正技术：选择输入日球地球物理指数的有效值，以及相对于F的临界频率对电离层模型进行线性相关校正。电离层2层。找到一点模型校正有效的域。他们确定了俄罗斯电离层观测网络对欧洲俄罗斯的当前覆盖范围。与没有校正的中位数模型相比，中位数模型的校正显着的区域显示为在中纬度处的纬度为7°，经度为15°。已经确定，主要不可能通过基于来自中纬度电离层观测点的数据进行校正来确定北电点和主要电离层槽区域内的点的电离层参数。在这些情况下，未经校正的气候模型更为有效。
