Description

In this paper, GPS transionospheric signals are used to study phase scintillation observations at the South African Antarctic polar research station. A multi-instrument approach shows that the scintillation events are associated with auroral electron precipitation. It is also demonstrated that substorms play an essential role in the production of scintillation in the high-latitude ionosphere.
