Swarm is the fifth Earth Explorer mission approved in ESA’s Living Planet Programme, and was successfully launched on 22 November 2013. The Swarm mission aims to provide the best-ever survey of the geomagnetic field and its temporal evolution, covering a wide variety of Earth processes, ranging from the geodynamo to the magnetosphere-ionosphere-thermosphere coupling using a constellation of 3 identical satellites carrying sophisticated magnetometers and electric field instruments. This session invites contributions illustrating the achievements of Swarm for investigating all types of Earth and near-Earth processes, as well as contributions describing synergies with other missions and ongoing initiatives towards designing innovative new low-Earth orbit (LEO) magnetic field missions.
