Most previous global induction studies have assumed simple structures of the source field and simplified models of the Earth, using mostly ground-based observations as data. This study presented a new approach to global induction studies using the data from Swarm geomagnetic satellite missions in order to infer the three-dimensional (3-D) conductivity structure of the mantle. The author suggested a consistent way of working with satellite geomagnetic data, the sources of the complex spatial structures, and full 3-D conductivity models. The author not only introduced the concept, but also developed and thoroughly tested a new modeling code to cope with the aforementioned challenges. This study has opened a door to new global induction studies.
The first author, Dr. Christoph Püthe, made the most significant contribution to this study. Therefore, we award him the 2015 EPS Award.
