Letter to the editor CUTLASS observations of a high-m ULF wave and its consequences for the DOPE HF Doppler sounder
International audience The CUTLASS (Co-operative UK Twin Located Auroral Sounding System) Finland HF radar, whilst operating in a high spatial and temporal resolution mode, has measured the ionospheric signature of a naturally occurring ULF wave in scatter artificially generated by the Tromsù Heater...
