内容記述 | Simultaneous measurements of the total geomagnetic field intensity at a few stations in Japan are compared. Non-local changes such as magnetic storm, Sq and the like cannot be removed by making simple differences between the values observed at two stations. After a number of trials, it is concluded that the best way of eliminating non-local changes is to make use of night-time data and to compute a weighted difference. The weight for a certain combination of stations is empirically determined. The smallest standard deviation of difference values thus estimated for stations in the central part of Japan amounts to 2.2 γ for an individual observation. The standard deviation could become smaller if we make use of averaged data during night-time only. Statistics separately made for disturbed and undisturbed days does not prove a marked contrast. The technique presented in this paper is going to be refined in the hope of detecting possible seismo-magnetic effect by proton precession magnetometer network covering Japan. | |||||
