Verification of the backward wave oscillator model of VLF chorus generation using data from MAGION 5 satellite.

Original language description

We present a detailed study of chorus emissions in the magnetosphere detected on board Magion 5, when the satellite was not far from the magnetic equator. We determine the frequency sweep rate of more than 8500 electromagnetic VLF chorus elements. Theseresults are compared with the backward wave oscillator (BWO) regime of chorus generation. Comparison of the frequency sweep rate with the BWO model shows: (i) There is correlation between the frequency sweep rates and the chorus amplitudes. The frequencysweep rate increases with chorus amplitude, in accordance with expectations from the BWO model; (ii) The chorus growth rate, estimated from the frequency sweep rate, is in accord with that inferred from the BWO generation mechanism; (iii) The BWO regimeof chorus generation ensures the observed decrease in the frequency sweep rate of the chorus elements with increasing L-shell.
