Multi-Instrument Studies of the Auroral Ionosphere
Abstract
New data collection modes and analysis techniques were developed which provide good time and spatial coverage and empirical models of the high latitude ionosphere have been developed and tested. 1) The first three-radar azimuth scanning experiment was performed combining observations from Millstone Hill, Sondrestrom, and EISCAT to produce maps of the convection electric field at high latitudes at 30 minute intervals throughout an interval of increasing disturbance. 2) Empirical models of the ionospheric convection electric field were developed from an extensive radar data base. 3) Quantitative models have been developed describing the distribution of the field-aligned currents which link the ionosphere and magnetosphere at high-latitudes. 4) A test of the local midnight-sector differences in the ionospheric convection models based on incoherent scatter radar data and those based on satellite observations was completed. 5) A new class of intense radar backscatter from the topside F region was identified as produced by parallel current-induced enhancement of the acoustic line. 6) The general characteristics of coherent radar backscatter from E region irregularities as observed with the Millstone Hill UHF radar was the subject of an intensive study.
