About the project

In a project funded by ESA (01 Sep 2015 - 31 Aug 2017) we develop a tool to monitor the size and shape of the plasmasphere based on satellite observations at low Earth orbit (at 300-500 km height). ESA Swarm mission consists of 3 identical satellites. Each of these satellites cross the plasmapause more than 60 times a day yielding an unprecedented possibility for monitoring the dynamic evolution of the plasmasphere.

The objectives of the current projects:

  • To develop a PP index: a proxy for the plasmapause position (equatorial radius). The PP position is determined from the magnetic signatures of small scale field aligned currents associated with PP (Heilig and Lühr, 2013).

  • To develop an empirical model of the PP based on Swarm observations.
