【摘要】 利用漠河站、左岭站、富克站垂测仪数据和COsMIC反演的电离层资料,分析比较了太阳活动高年两种探测手段获取的电离层特征参量（N_mF₂、h_mF₂）的相关性.结果表明,两种方式获取的电离层对应特征参量相关性较高,且N_mF₂的相关性好于h_mF₂,同时相关性与纬度和季节有关.在地磁中纬度地区对应参量相关性较好,而在地磁低纬度受北驼峰控制区域相关性降低;在电离层赤道异常区域,春秋季、夏季对应特征参量相关性好于冬季.造成冬季相关性低的可能原因是,在跨越赤道中性风作用下,冬季电离层赤道异常区电子浓度梯度较大,造成掩星反演误差增大,致使两种探测手段获取的电离层特征参量相关性降低.更多还原

【Abstract】 This study aims to comparing the ionospheric character parameters（N_mF₂,h_mF₂） from Digisondes over China with data from the FORMOSAT-3/COSMIC satellites during 2012（the solar maximum）.Data from three Chinese Ionosonde stations located in Mohe（52.0°N,122.5°E）,Zuoling（31.0°N,114.5°E） and Fuke（19.4°N,109.0°E） were used in the comparison.The results show that the correlation of the corresponding ionospheric parameters is pretty good and the N_mF₂ has a better correlation than h_mF₂ has,and the correlation coefficient changes with the latitude and season.The correlations of both N_mF₂ and h_mF₂ in middle geomagnetic latitudes are higher than those in equatorial ionization anomaly.The correlation coefficients in equatorial ionization anomaly in winter are lower than those in other seasons.The possible reason is that the electron density gradient during winter in the equatorial ionization anomaly is stronger than other seasons.更多还原
