Swarm DISC

The objective of the Swarm mission is to provide the best ever survey of the geomagnetic field and its temporal variation. In the framework of the mission, ESA is supporting the implementation of processing chains to provide up-to-date models or time series of various contributions to the magnetic field – e.g. core field, lithospheric field, ionospheric and magnetospheric fields. Two types of processing chains have been developed: Cat-1 chains use complex and mature algorithms and require a “Scientist-in-the-Loop” to drive the processing chain, Cat-2 chains are based on simpler algorithms and aim at providing data with minimum delay for various applications – e.g. Space weather. During the data exploitation phase the Cat-1 chains will be run in scientific institutions under the control of qualified scientists, whereas the Cat-2 chains will be run automatically by ESA.

Outside GFZ, several European institutions are involved in the project: Technical University of Denmark (DTU), l’Institut de Physique du Globe de Paris (IPGP), the British Geological Survey (BGS), Delft Institute for Earth-Oriented Space research (DEOS) and the Swiss Federal Institute of Technology Zurich (ETH).

The GFZ has the responsibility to develop several processing chains:

  1. Dedicated core field modeling including estimation of the Euler angles (DCO -- Cat-1)
  2. Total Electrical Content (TEC – Cat-2)
  3. Ionospheric Bubble Index (IBI – Cat-2)
  4. Ionospheric Field Aligned Currents (FAC – Cat-2)
