摘要:
利用2006~2010年云南东部地区9期地磁三分量观测资料,经过日变改正、长期变化改正消除地磁场的日变化及长期变化影响,计算各期地磁内源场的曲面样条模型并剥离出地磁异常场分布,求解相邻两期地磁异常场差异获取地磁异常场的变化,并对磁异常场中磁偏角分布的变化进行了描述。
Abstract:
Using nine-term of three-component geomagnetic data observed in the eastern area of Yunnan Province from 2006 to 2010,we eliminate the effects of the diurnal variation and the secular variation of the geomagnetic field through correction,calculate each term's surface spline model of the interior geomagnetic field,separate the distribution of the geomagnetic anomalous field,and get the differences between two successive terms of the geomagnetic anomalous field and acquire the variation of the geomagnetic anomalous field.Finally,we describe the variation of the distribution of the geomagnetic declination in the geomagnetic anomalous field.
