The Global Distribution of RF Emission in the Topside Ionosphere and High Energy Particle Precipitation

The electromagnetic emission in the topside ionosphere has been investigated since a first satellite were located on the orbits. The RF measurements can be used to diagnose the different electron plasma waves as well as the electron ionospheric density. The paper presents the global picture of RF radio noises in 0.1-15 MHz frequency range and high energy electron (0.5-1.24 MeV) and protons (I-30.0 MeV) detected on board of low orbiting satellite CORONAS-I. The well manifested global distribution features of the observed spectra appears as remarkable enhancement of spectral density over Europe and part of Asia. The aim of this paper is to present relations between the global map of RF emission and energetic particle precipitation pattern. (author)
