Radiation belt electron dynamics driven by VLF transmitter waves in near-Earth space

Very-Low-Frequency (VLF) transmitters operate worldwide typically at frequencies of 10–30 kilohertz and are well known to drive important electron precipitation in the near-Earth space environment. While it has been of intense scientific interest and practical importance to understand whether VLF transmitters can affect the natural environment of charged energetic particles, for decades there remained little direct observational evidence that revealed the effects of these VLF transmitters in geospace. In addition, although many efforts have been made to investigate the role of VLF transmitters in electron losses, the capability of VLF transmitters to accelerate radiation belt electrons has mostly been assumed to be negligible and overlooked. In this seminar, based on both observations from Van Allen Probes and two-dimensional Fokker-Planck diffusion simulations, I will discuss the quantitative role of VLF transmitters and other naturally occurring plasma waves in both electron loss and acceleration in the inner belt and slot region. Out study reveals that VLF transmitter waves can simultaneously accelerate higher energy electrons and drive electron loss at lower energies.
