Advanced Modelling of Geospace (AMOG) Using Satellite Platform Magnetometers

Continuous monitoring of electric current systems in Earth’s environment, including the ionosphere and magnetosphere, is essential for characterising geospace. Such observations are required, for example, to determine the energy input into the upper atmosphere and to monitor disturbances in the space environment and associated hazards. This monitoring can be achieved through magnetic field measurements acquired both on the ground and in space.

The spatio-temporal sampling provided by dedicated magnetic satellite missions such as Swarm and MSS can be significantly enhanced by incorporating platform magnetometer data from non-dedicated missions, including CryoSat-2, GRACE, and GRACE-FO.

This presentation reports recent achievements in the use of platform magnetometer data within a study funded by ESA’s General Support Technology Programme (GSTP). In particular, it highlights the calibration and provision of magnetic field data from ESA’s Aeolus satellite.
