Interpolate the magnetic field data during the geomagnetic storm

This paper aims to interpolate the magnetic field data, which needs to be utilized to assess the potential disrupt caused by the geomagnetic storm. The available magnetic data is very sparse over the Earth's surface. To address this issue, this paper proposes an interpolation method that takes the magnetic field inherent characteristics into account. The real magnetic data over a three-month period is analyzed and the dependencies between the observatories are extracted and these interdependencies are eventually considered in the interpolation and higher performance is achieved.
