Swarm, a constellation mission comprising three identical satellites, was launched in November 2013. It has been used to survey the geomagnetic field and its temporal evolution to an unprecedented level of accuracy, and to investigate the interaction of the geomagnetic and electric fields with the Earth system and near-Earth space.

The three Swarm satellites make high-resolution measurements of the strength, direction and variation of the magnetic field, complemented by precise navigation, accelerometer, plasma and electric field measurements. Its constellation configuration has enabled observations of the gradients within the geomagnetic field, ionospheric and thermospheric parameters, and the gravitational field. Since 2013 the two lower satellites flying side-by-side with an initial altitude of 460 km have decreased in orbital height. The third satellite, at a higher altitude, has separated from the lower two in local time by few hours.

This session solicits contributions about recent scientific results from the mission in terms of data analysis and Earth science applications with a focus on the exploitation of the gradient information and diverging local time measurements achieved by the Swarm mission. General contributions on results using Swarm data, in combination with other satellite missions or ground observations are also very welcome.
