中国电离层 f0F1与国际参考电离层的比较

Comparison of f0F1 Observed in China with the IRI

本文对我国八个电离层垂测站,在第二十和二十一两个太阳活动周(1967～1986年)中二十年实测 f_0F_1资料与 IRI 计算结果进行了系统的分析比较。指出将IRI 用于我国计算 f_0F_1时,其数值大小偏差较小,而 F_1层的出现时间与实测结果差别较大。为此,提出了更加适合我国情况的建议。

A comparison is made between the f_0F_1 at eight Chinese ionospheric observatories during the 20 th and 21st solar cycles,and that given by the International Reference Ionosphere.Although small discrepancy is found between the two series of values of f_0F_1,F_1 occurs much more often in China than the predicted in IRI.A suggestion for improving the description of F_1 layer occurance in China region has been put forward.
