Satellite geomagnetism
We analyse observations from three past satellite missions Oersted, CHAMP and SAC-C as well as ongoing ESA Swarm mission using the data to construct improved models of the core and crustal field, to carry out mantle induction studies, and to better characterise secular variation especially at short time and length scales.
