摘要
中国大陆构造环境监测网络(陆态网络)是中国最大的GPS综合服务网络,该网络包括260个分布全国的GPS基准站。本文首先介绍了利用GPS研究电离层TEC的基本原理与方法,然后阐述了陆态网络电离层TEC监测系统的数据处理及产品发布的详细流程,最后分析了震前电离层异常现象与地震发生的耦合关系,并利用陆态网络电离层TEC监测系统的产品分析了四川省芦山7.0级地震的同震电离层扰动现象。
rustal Movement Observation Network of China （CMONOC） is the biggest inte- grated service network in China, and contains 260 GPS stations. In this paper, the basic principle and method of studying ionospheric TEC by GPS is firstly introduced , then the flow of data processing and product release of CMONOC monitoring ionospheric TEC sys tern is detailedly explained. In the end, the coupling relationship between ionospheric a- nomalies before earthquakes and earthquake occurrence is analysed. And coseismic iono- spheric disturbances of the MsT. 0 Lushan earthquake is analysed by using the products of CMONOC monitoring ionospheric TEC system.
