Recent experimental campaigns with the SPEAR high power system on Svalbard have succeeded in generating heater-induced backscatter simultaneously on the Finland and Iceland CUTLASS HF radars. The high-power, high time resolution, low spectral width backscatter has been used to generate vector measurements of the wave’s ionospheric electric fields, which enable the determination of the characteristics of such naturally-occurring ULF wave activity over Svalbard. Both large-scale field line resonances, and small scale wave activity associated with magnetospheric wave-particle interactions have been observed. The characteristics of such waves at the very high latitudes of Svalbard will be compared with predictions.
