On the determination of lower ionospheric perturbations detected as fast amplitude variations of VLF signals
We analyze the occurrence of very low frequency (VLF) events and their association with geomagnetic activity. VLF events are detected as fast amplitude variations of VLF signals from Hawaii (NPM Navy transmitter) and received at Comandante Ferraz Brazilian Antarctic Station (EACF) in the period from...
