Study and Analysis of Equatorial Irregularities, Total Electron Content, and Scintillations.

Abstract

The following are among the topics studied. (1) The nature of electrojet irregularities responsible for daytime VHF scintillations in the equatorial region. The times of onset and decay of VHF scintillations are shown to correspond closely with the times of onset and decay of type 2 irregularities deflected by 50 MHz radar and E sub sq echoes on ionograms. (2) The spatial localization of nighttime irregularities detected by scintillation and VHF radar backscatter measurement; (3) The kilometer and meter scale irregularities in the night-time equatorial F-region giving rise to VHF-UHF scintillations and VHF radar backscatter; (4) Modelling of equatorial and high latitude scintillations using a large data base, and also the detailed, individual magnetic storm picture; (5) The variability of total electron content (TEC) as it limits the accuracy of satellite navigation and satellite detection radar systems as well as the correlation distance of TEC variability. The results of plasmaspheric electron content are presented and its importance in the determination of additional ionspheric group delay is assessed.
