Ground-based very-low-frequency radio wave observations of energetic particle precipitation

Popis výsledku v původním jazyce

At very low frequencies (15–50 kHz) man-made radio-wave transmissions from communication transmitters tend to dominate over lightning-generated noise. Perturbations of the amplitude and phase of fixed-frequency subionospheric very-low-frequency (VLF) transmissions can be associated with excess ionization occurring in the 50–90-km altitude range. Energetic particle precipitation resulting from loss processes occurring within the magnetosphere can produce such perturbations. The global Antarctic-Arctic Radiation-belt (Dynamic) Deposition-VLF Atmospheric Research Konsortia (AARDDVARK) network of VLF receivers can be used to determine some of the characteristics of energetic particle precipitation. The overlapping pattern of propagation paths provided by the >20 AARDDVARK sites potentially allows precipitation patch dimensions to be determined. Several case studies of electromagnetic ion cyclotron (EMIC)–induced electron loss from the outer radiation belt are discussed in this chapter, piecing together a complex picture of EMIC-driven precipitation lasting many hours and over a wide range of longitudes.
