全球电离层图和国际参考电离层在中国区域的评估

摘要

根据全球电离层图和国际参考电离层两种常用的电离层模式,对2011年中国区域三个电离层测高仪的观测数据进行了分沂,并对其进行比较.结果表明全球电离层图比国际参考电离层能够更好地反映电离层电子含量的变化,而国际参考电离层当前最新版本IRI2011的精度比IRI2007的有了较大提高.%The global ionospheric maps and international reference ionosphere as common ionosphere model are described.Observations in 2011 derived from three ionosondes in China are analysed.Comparative analysis between the measured data in China with global ionospheric maps and international reference ionosphere are represented in the work.The result indicates that global ionospheric maps is better than international reference ionosphere to describe the variation of electron content of ionosphere,and the accuracy of IRI2011 which is the latest version of international reference ionosphere is much higher than IRI2007.
