ELECTRON CONTENT VARIATIONS IN THE AURORAL IONOSPHERE DETERMINED FROM SATELLITE RADIO OBSERVATIONS,
Abstract
The relationship between (1) spatial distri bution of ionization using 20 and 40 mc/s transmissions from a satellite, (2) the location and luminosity profiles of auroras as measured from ground stations in Alaska, and (3) the flux and energy spectrum of particles penetrating to auroral height as measured by satellite instru ments is reported. The experiment was carried out in March, 1962 using a polar orbiting satellite which made twelve passes over Alaska during its operational lifetime. The emphasis of this work is on the determination by radio techniques of the variation of electron content in the ionosphere connected with incident parti cle fluxes. Methods of determining the electron content from differential Doppler measurements are discussed in detail. The experimental re sults show that increases in electron content are morphologically correlated with regions of auroral luminosity and incident particle fluxes. The results of the experiments also point out the value of conducting coordinated expe-ents in the study of auroral phenomena. (Author)
