High-time resolution geomagnetic data obtained at Mineyama station are analyzed to examine the secular variation of geomagnetic transfer function. The results are compared with those estimated from the data observed at Kakioka and Shigaraki stations. Wavelet transform is applied to detect the Pi2 type geomagnetic micro-pulsations, and the data for the period of Pi2 pulsations are used to calculate the transfer function. The results indicate a variation in the transfer function for short period… CONTINUE READING
