Nonlinear phenomena in whistlers

  1. Institute of Cosmophysical Researches and Radio Wave Propagation FEB RAS, Russia

   In the result of experimental observations, carried out at "Paratunka"
   observatory (53.02N, 158.65E; L=2.3), synchronized with HAARP complex
   (62.30N, 145.30W; L=4.2), an atypical form of whistlers was determined.
   This form is likely to be determined by amplitude modulation of
   electromagnetic pulse of about 1 second long with the filling frequency of
   about 1.1 kHz, applied in the experiments on energetic particle controlled
   precipitation from the Earth radiation belts. An approach to estimate
   plasma parameter variations in the magnetosphere on the basis of the
   discovered effect was suggested.
