Swarm Science Results after two years in Space

Edited by: Nils Olsen, Claudia Stolle, Rune Floberghagen, Gauthier Hulot, Alexey Kuvshinov

Swarm, a three-satellite constellation mission to study the dynamics of the Earth's magnetic field and its interactions with the Earth system, has been in orbit since November 2013. This special issue reports high quality scientific results from the first two years of the mission, including investigations of the Earth’s magnetic and gravity fields, their sources and of the way these interact with the Earth’s environment.

    Prompt penetration electric fields and the extreme topside ionospheric response to the June 22–23, 2015 geomagnetic storm as seen by the Swarm constellation

    Using data from the three Swarm satellites, we study the ionospheric response to the intense geomagnetic storm of June 22–23, 2015. With the minimum SYM-H excursion of −207 nT, this storm is so far the second str...

    Localized field-aligned currents and 4-min TEC and ground magnetic oscillations during the 2015 eruption of Chile’s Calbuco volcano

    The Calbuco volcano in southern Chile erupted on April 22, 2015. About 2 h after the first eruption, a Swarm satellite passed above the volcano and observed enhancement of small-amplitude (~0.5 nT) magnetic fl...

    Scale analysis of equatorial plasma irregularities derived from Swarm constellation

    In this study, we investigated the scale sizes of equatorial plasma irregularities (EPIs) using measurements from the Swarm satellites during its early mission and final constellation phases. We found that wit...

    Recent geomagnetic secular variation from Swarm and ground observatories as estimated in the CHAOS-6 geomagnetic field model

    We use more than 2 years of magnetic data from the Swarm mission, and monthly means from 160 ground observatories as available in March 2016, to update the CHAOS time-dependent geomagnetic field model. The new mo...
