GP43C:
Swarm Two Years on: Achievements in Unraveling the Earth's Magnetic Field II Posters


Session ID#: 8382

Session Description:
Swarm is an Earth Explorer mission in ESA's Living Planet Programme launched on November 22, 2013 and is dedicated to geomagnetic field exploration. The mission is composed of a lower satellite pair flying in a side-by-side constellation, with a third satellite in an independent higher orbit. The three spacecraft deliver high-accuracy measurements of the strength, direction and time variations of the magnetic field, providing the required observations to unravel the magnetic signals that stem from Earth’s core, mantle, crust and oceans, as well as its ionosphere and magnetosphere.

This session solicits contributions about the results from the mission two years after its launch in terms of data analysis, modeling and interpretation as well as combination and synergies of Swarm with other satellite missions and ground stations in order to provide a comprehensive description of geomagnetic field sources and their variations.
