基于JSCORS的区域电离层时空特征分析

摘要

本文利用JSCORS中心提供的连续两天的GPS观测数据,以及现有的提取垂直电离层延迟改正VTEC的软件,采用格网技术和常规单层VTEC模型,内插计算出区域格网的时空数据,对所得数据进行处理分析,得出了江苏南京附近大气层中电离层较为明显的特征。文章总结了该区域电离层的时空变化特征,为后续研究电离层更加细化的特征及其在各方面的应用等提供了依据。%In this paper,by using the GPS observation data lasts for two days provided by JSCORS center and the existed software to calculate the vertical ionospheric delay correction,the paper apply the Grid technology and the conventional single-VTEC model,then interpolation to calculate the spatial and temporal data in the regional grid.At last,the paper give the final data an analysis and the conclusion that the ionosphere has distinctive features in the region nearby Nanjing,Jiangsu Province.Writing this paper is to pave the way to the follow-up studies which will be more deeply.
