Swarm is the fourth Earth Explorer mission of European Space Agency (ESA) launched on 23 November 2013. The final constellation of the three-satellite mission with two spacecraft (Swarm A and C) flying side by side at low altitude (~ 460 km) and one (Swarm B) flying at a slightly higher altitude (~510 km) was achieved on 17 April 2014. The mission measures the geomagnetic field by identifying and measuring magnetic signals from Earth’s core, mantle, lithosphere, oceans, ionosphere and magnetosphere. Additionally, Swarm data are used to study the Sun’s influence on Earth system by analysing electric currents in magnetosphere and ionosphere and understanding the impact of solar wind on dynamics of the upper atmosphere. Swarm currently offers one of the best-ever surveys of the Earth’s main and crustal magnetic field as well as the near-Earth electromagnetic environment. This session solicits contributions about recent scientific results from the mission in terms of internal and external magnetic field studies and in combination with other satellite missions or ground observations.
