A COMPARISON OF THE MAIN IONOSPHERIC PARAMETERSOVER CHINA WITH IRI
-
摘要: 本文利用我国满洲里、北京、武昌、重庆和广州等台站电离层观测记录,对各层临界频率的实测值(月中值)与IRI-86的计算值进行了分析比较.|发现两者存在着显著而系统的偏离.E层和F1层偏离较小F2层偏离较大,其相对值有时超过60%.总的来说,f0F2的相对偏离:夜间大,白天小冬季大,夏季小太阳活动低年大,高年小随着纬度降低偏离增大模式值普遍大于实测值.

Abstract: By using the ionosonde data observed at several observation stations in China, the observed values of f0F2, f0F1 are compared with that of IRI-86. The study showed that there exist a systematical and obvious deviations between them. The deviations for E- and F-region are somewhat small. However, the deviation for F2-region is considerably large, even being up to 60% in some cases. The deviations show clearly diurnal, seasonal and solar activity variations. In general, the relative deviations for f0F2 in the night time, summer and active solar zear. Moreover, the deviations become larger with decreasing latitude, and the values calculated from IRIare usually larger than the observed ones.
