国际参考电离层IRI－90与中国实测电离层月平均电子密度剖面形状的比较

A COMPARISON OF THE INTERNATIONAL REFERENCE IONOSPHERE(IRI-90) WITH THE ELECTRON DENSITY PROFILE OF THE IONOSPHERE OBSERVED IN CHINA

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．

A systematic 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.
