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。
In order to studying the means of monitoring and predicting to solar flare, the observation data of more than 60 global GPS tracking-station 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.
