The 4D-Earth-Swarm project
The goal of the 4D-Earth-Swarm project, supported by the European Space Agency, is to improve our understanding of the rapid (interannual) changes in the geomagnetic field, as recorded by the three satellites of the Swarm mission of ESA - as well as earlier satellite missions and ground-based observatories. The work also involves input from state-of-the-art numerical simulations of the geodynamo. Full details on the project can be found after this link.
