利用2000-2006年南极中山站GPS观测数据,研究中山站电离层TEC随太阳活动、地磁环境、单日、年和季节变化的特征.结果表明,GPS-TEC随太阳活动和地磁环境的影响呈线性变化特征,单日、年和季节性TEC变化表现出电离层气候学特征的同时,也出现了磁中午异常的极区特性.
利用2000-2006年南極中山站GPS觀測數據,研究中山站電離層TEC隨太暘活動、地磁環境、單日、年和季節變化的特徵.結果錶明,GPS-TEC隨太暘活動和地磁環境的影響呈線性變化特徵,單日、年和季節性TEC變化錶現齣電離層氣候學特徵的同時,也齣現瞭磁中午異常的極區特性.

Precise ionosphere TEC values are derived from perennial GPS observations during 2000-2006 at Antarctic Zhongshan station, the characteristics of TEC associated with solar activities,geomagnetic environment, and the daily, annual and seasonal TEC variations are studied.Results show that GPS-TEC linearly changed with the influence of solar activities and geomagnetic environment while climatologic characteristics of ionosphere are reflected in daily, annual and seasonal TEC variations, as well as polar characteristics of magnetic noon anomaly occurr.
