Cluster Tunes Into Earth’s Frequency, Pinpoints Location of Auroal Radio Emissions

Researchers have known for three decades that the Earth is a potent radio transmitter, but they were never able to pinpoint where the noise was coming from. By using data from the four spacecraft of ...

Quasiperiodic Very Low Frequency Emissions in the Earth's Magnetosphere

Quasiperiodic (QP) very low frequency (VLF) emissions are intermittent bursts of electromagnetic energy, observed in the frequency range of approximately 3–30 kHz, that recur at quasi-regular ...

Artificial modification of Earth’s radiation belts by ground-based very-low-frequency (VLF) transmitters

Narrow-band VLF transmitter waves originate from the powerful ground-based VLF transmitters for submarine communications, which are typically over the frequency range of 10–30 kHz. VLF transmitter ...
