Title Interplanetary Scintillation and Space Weather Monitoring
Abstract Interplanetary scintillation (IPS) is a technique that allows us to remotely sense the plasma number density in the inner heliosphere. Thus, using IPS, we can track density structures propagating out from the Sun and should be able to predict their time of arrival at the Earth. Since these structures carry the enhanced fluxes of momentum and energy that drive geomagnetic activity, IPS measurements are potentially an important space weather activity that can help to predict the onset of geomagnetic activity. However, in practice, IPS has proved disappointing as a means of predicting geomagnetic activity. In this paper, we briefly review results obtained from the Cambridge IPS array during 1990-93 with a focus on those results that are particularly relevant to space weather. We also discuss some of the limitations that have made IPS so disappointing and suggest ways in which these limitations might be overcome in a future IPS system.
