| 摘 要： | 基于磁扰期间地磁扰动的时间变化特点,提出了一种磁扰日地磁日变改正方法-扰日法,该法充分利用磁扰日前后的日变观测资料,将磁扰日期间的静日变化和扰动变化分离,结合各自的时间特点,分别对其进行改正。实例验证与分析表明:磁扰期间,采用扰日法可以提高磁扰日地磁日变改正精度,并且其日变改正精度与时间差(经度差)不存在相关性。

| Abstract: | Based on the temporal characteristics of the disturbance,the disturbed variation correction method during the disturbance has been given out.The observed data before and after the disturbance have been well analyzed, and the quiet variation have been effectively separated form the disturbance during the disturbance.Combined with the temporal characteristic of each variation,the reasonable diurnal variation correction value will be obtained.The conclusion shows that the method can greatly improve the precision during the disturbance. |
