Some Challenges of Geomagnetism Addressed with the Use of Ground and Satellite Observations

Abstract —The continuous growth of geomagnetic observations requires adequate methods for their processing and analysis. On the other hand, many studies in the field of geomagnetism require accurate and reliable measurements from both ground and space. Mathematical methods of geoinformatics can provide a solution to these problems. The article describes the progress made in the field of intellectual analysis of geomagnetic data continuously recorded by magnetic observatories and low-orbit satellites, demonstrates the results in the study of rapid variations of the Earth’s core magnetic field associated with the processes in the Earth’s deep interior, and presents the investigation of near-Earth electromagnetic dynamics. The applied value of the obtained results is also shown.
