dc.description.abstractThe data from Super Dual Auroral Radar Network (SuperDARN) radar and Cluster was used to investigate whether the processes observed by SuperDARN radar in the highlatitude ionosphere leads to the processes that take place in the magnetosphere. SuperDARN is a global network of high-frequency coherent-scatter radars operating in the northern and southern hemispheres and these radars are capable of observing backscatter from ionospheric irregularities. The Tsyganenko T96 field model was used to map the footprint of the Cluster spacecraft into the ionosphere. The SuperDARN radar data analysis software was used to generate time series, fi eld of view and convection plots. The data from Syowa South, Syowa East SuperDARN radars, Advance Composition Explorer (ACE) and Cluster spacecrafts was used in this study. Two events were found and discussed, an event on 09 August 2002 and another event on 30 September 2002. The SuperDARN radar and Cluster data for these events were compared. When a change in electric field was observed by Cluster, SuperDARN radar observed a change in the convection flow. There was a time delay between the change in the electric fi eld and the change in convection flow.en
