A Fourier transform is performed on each segment, and the color shows the magnitude of the signal. The numerous vertical lines on these spectrograms are radio atmospherics, or `sferics’, originating from lightning strikes, which could be anywhere in the world. Lightning emits short bits of impulsive radiation which can observed be at global distances from the source since they are guided by the Earth-ionosphere waveguide. These correspond to the “click” and “tweek” sounds in the audio sample. A zoom-in a radio atmospheric is shown in the bottom left panel. There are also a set of short horizontal lines between 10 and 15 kHz. These are the `Alpha’ navigation beacons. The solid horizontal lines between 18 and 30 kHz are VLF transmitter signals, although they are too high in frequency to hear in the audio. Elf Balayı.

ELF/VLF waves give us the only reliable and continuous means of monitoring the lower ionosphere, and thereby, inferring communications outages. For instance, we can monitor ionospheric communication outages from gamma ray bursts from outer space. Satellite protection. When satellites are launched into space, they are immediately bombarded by a population of energetic charges particles that are trapped by the Earth’s magnetic field, called the Van Allen radiation belts. Over time, these particles can degrade and destroy satellite electronics. In periods of strong solar activity, the number of energetic particles can go through the roof, and stay there for years. ELF/VLF waves from lightning has been shown to be a key driver of the removal of these trapped particles, by propagating as a `whistler’ wave (named for how it sounds in an audio playback) through the magnetosphere, and the Stanford ELF/VLF group is active engaged in understanding how this process works, through experiments and theoretical modeling. Read more about our studies of lightning-induced electron precipitation as observed on the ground, or or in space, or our active experiments to reproduce this effect with VLF radio stations.

The first operators reported hearing bizarre sounds that they described as clicks and tweeks, particularly on a day with lightning, which we now know were probably just sferics being picked up by their telegraph line, basically acting like an antenna. Later, in World War I, soldiers operating communication lines reported hearing strange sounds consisting of a falling tone, sounded like someone was whistling. “You can hear the grenades falling” some used to say. What they were really hearing was an indirect version of lightning energy, known today as whistler, coupling into the communication lines. Show Me Some “ELF/VLF Data”, Please. The history of ELF/VLF research had its start mostly in audio recordings, since ELF and VLF studies fall in the 300 Hz – 30 kHz, the frequencies range the human ear can recognize. Early ELF/VLF researchers would simply play the signal received by an antenna straight through a speaker.
