A COMPARISON OF THE INTERNATIONAL REFERENCE IONOSPHERE(IRI-90)WITH THE ELECTRON DENSITY PROFILE OF THE IONOSPHERE OBSERVED IN CHINA
-
摘要: 将太阳活动峰年期间中国4个电离层站垂直探测得到的月平均电子浓度剖面与国际参考电离层IKI-90进行了系统的比较。结果表明国际参考电离层所计算的峰下电子含量(或峰下半厚)总体来说偏大。一天中白天符合较好,晚上较差,对中纬台站较好,对低纬台站较差。Abstract: Asystematic comparison is made between the electron density profiles observed at four of the Chinese ionospheric stations during high solar activity periods and the International Reference ionosphere IRI-90.It is indicated that the bottomside values of IRI-90 are generally greater than measured ones. In detail, the IRI-90 predicted electron content values are more close to the measured ones in daytime than in nighttime, and more close at mid latitudes than at low latitudes.
