- 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.
