| 摘 要： | 本文探讨了应用最小曲率原理由单站微分多普勒频移数据计算TEC时所遇到的问题和解决办法。处理了用MX1502大地定位接收机于1989年8月和9月先后在陕西临潼和北京观测的NNSS卫星多普勒频移数据,得到了TEC时空分布曲线。分析这些曲线,得到了TEC赤道异常北驼峰时空特征在太阳活动高年(尤其是8月中旬太阳特大质子事件中)的某些结果。

| Abstract: | In this paper some proplems in using differential Doppler data to calculate TEC by means of the minimum curvature method are discussed and analysed, and the procedure to solve the problems is also given. Using the procedure processed the NNSS satellite Doppler frequency shift data obtained in Lintong and Beijing on August and September 1989, by the MX1502 receiver, and get the distribution curves of the TEC. From the curves some interesting results about spatial and temperal features of the equatorial anomaly during high solar activity years, expecially during the solar great proton event on 13 August 1989, are found. |
