摘要: 为利用GPS对太阳耀斑进行监测和预报研究,从IGS网站上下载了全球分布的60多个GPS跟踪站的观测数据,对两起X级的太阳耀斑爆发时所引起的TEC变化进行了计算及分析。结果表明,中低纬度的GPS跟踪站在太阳耀斑发生期间均监测到了总电子含量的突增现象,并且与X射线辐射通量图具有很好的一致性;差分TEC可以获得更精细的总电子含量的变化情况,更加适合于对太阳耀斑的细致研究;通过对相邻日绝对总电子含量的研究发现,在耀斑爆发前期,相邻日绝对总电子含量会出现大幅度的跳跃现象。Abstract: In order to studying the means of monitoring and predicting to solar flare,the observation data of more than 60 global GPS trackingstation from IGS is downloaded,TEC that coming from two solar flare of X level is calculated and analyzed.The results show that the sudden increasing phenomenon of TEC is monitored in solar flare,which all GPS tracking-stations locate the high latitude area and the low latitude area,and it is consistent with the figure of X ray flux;difference TEC can gain more exact change of total electron content,so it adapts to the detailed study of solar flare;the phenomenon of TEC great range jumping is discovered in studying absolute TEC range between closer-day,so the experimental viewpoint and conclusion are obtained.
