Satellite measurements of plasma-density perturbations induced in the topside ionosphere by high-power HF radio waves from the “Sura” heating facility
Abstract
We report on the French DEMETER and American DMSP satellite measurements of largescale field-aligned plasma-density perturbations (ducts) induced in the topside ionosphere by the ionospheric F 2-layer pumping by means of high-power HF radio waves from the “Sura” heating facility. Characteristics of such plasma perturbations and conditions of their formation are determined.
