Modeling and Forecasting of the Variable Geomagnetic Field at Multiple Time Scales

摘要：

The variable geomagnetic field contains a variety of components from various sources. It has different variation characteristics at each time scale. In this paper, a method of modeling and forecasting the variable geomagnetic field at multiple time scales is presented. Firstly, we develop a magnetic trend variation model at day scale, a magnetic daily variation model at hour scale, and a short period variation model at minute scale, respectively. Then, we combine each model of different time scale to realize the modeling and forecasting of the variable geomagnetic field. The method combines the physical origin of the variable geomagnetic field and fuses multiple models to obtain both long forecasting time span and high forecasting precision.
