Propagation of LF and VLF waves and their use for monitoring space weather...

Electromagnetic waves with wavelengths from 1 to 100 km, or correspondingly in the frequency range between 3 and 300 kHz, are denoted by low frequencies (LF) and very low frequencies (VLF). Their signal propagation is determined significantly by the state of the ionosphere. Only because of its predominating...
