Interplanetary Scintillations as a Tool for Synoptic Monitoring of Space Weather

Peter Duffett-Smith and Graham Woan

Abstract:	Interplanetary scintillation provides a powerful groundbased method of measuring the total electron content along a line of sight through the solar wind. Regions of enhanced density, such as interplanetary shocks, can cause geomagnetic activity when they hit the Earth, which in turn can disturb the ionosphere, causing uncalibrated range errors and in severe cases, total loss of service in GNSS. A system of linked antenna arrays spaced around the Earth could provide, typically, 24 hrs forecast of an impending geomagnetic event which would be of benefit to high-integrity users of GPS.
