Scientific paper

Controlled experiments with ground-based ELF/VLF transmitters have proven invaluable in studying the interactions between whistler waves and energetic electrons in the radiation belts. These gyrosesonant interactions result in wave growth and nonlinear triggered emissions that can be observed both at the geomagnetic conjugate point after reflection and a second interhemispheric crossing. Most notably, the Siple Station transmitter in Antarctica at L=4.6, which operated at 0.5-5 kHz from 1973-1988, provided a wealth of examples that still have not been analyzed on a large scale. In 15 years of experiments, Siple Station transmitted a broad array of frequency-time formats, including tones, ramps, tone doublets, and chirps, under a variety of geomagnetic conditions. To enable more thorough and longer-term studies, data are now being digitized in mass from magnetic tapes, with additional processing to remove artifacts of the recording and digitization. We present initial statistics on the occurrence of amplified ELF/VLF waves at the conjugate location to Siple, Roberval, Quebec, and the signal near Siple Station after a second interhemispheric crossing. Using the transmitted tones and ramps, we analyze the correlation of the growth rates of ELF/VLF waves injected at Siple Station and the L-shells of the propagation paths with geomagnetic parameters (kp, ae, etc).
