摘要(Abstract)：

针对国际GNSS服务(IGS)各电离层分析中心发布的全球电离层图(GIM)在南极地区精度有限的问题,该文在收集IGS、极地对地观测网络(POLENET)计划和中国南极测绘研究中心(CACSM)的GPS数据的基础上,采用球冠谐分析理论建立了南极地区电离层电子总含量(TEC)模型。通过球冠谐分析的零阶项系数表示的日均值与实测TEC日均值的对比,表明二者具有很强相关性,验证了球冠谐分析具有良好的物理意义,可以有效提取南极电离层的周期特征。利用球冠谐函数模型对全南极电离层在2012年季节变化、空间分布和10月地磁暴期间的响应特征进行了分析。实验结果表明,基于球冠谐分析构建的电离层模型更适用于探测南极电离层的特征。
