New data-collection modes and analysis techniques were developed that provide good time and spatial coverage and empirical models of the high latitude ionosphere. (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 were developed describing the distribution of the field-aligned currents that 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.
