초록
We investigate the time-variational characteristics of power spectrum and transfer function of geomagnetic field by robust estimation technique. In the case of power spectrums of geomagnetic field, there are some the periodic fluctuations related with solar activity, Meanwhile, the geomagnetic transfer function shows so considerable weak time-variational fluctuation that the estimations of transfer function seem to be comparatively stable in time-variant view.
