Morning sector drift-bounce resonance driven ULF waves observed in artificially-induced HF radar backscatter
HF radar backscatter, which has been artificially-induced by a high power RF facility such as the EISCAT heater at Tromsø, has provided coherent radar ionospheric electric field data of unprecedented temporal resolution and accuracy. Here such data are used to investigate ULF wave processes observed...
