“…Thus, the subsequent motion of the barium ions may be measured by ground-based optical techniques, and the perpendicular ionospheric electric field deduced from its influence on the trajectory of the cloud. In this way more than 100 barium cloud measurements of electric fields in the ionosphere have been made [28,29,30,31,32,33,34]. The motion of the ion cloud perpendicular to/~ is related to the perpendicular ionospheric electric field in a complex fashion.…”

Methods for measuring the amplitudes and directions of DC electric fields and the directions, power spectra, and dispersion relations of AC electric fields in the magnetosphere are discussed with emphasis on their applicability in various regimes of the magnetospheric plasma.. The two classes of techniques that are discussed are measurement of the bulk flow of the plasma and the potential difference between pairs of separated conductors. The plasma bulk flow discussion includes measurements by ionospheric radar backscatter, whistler mode wave propagation, energetic or thermal particle trajectories, artificial ion cloud motion, probe measurements of bulk flow, vehicle wake analyses, effects of bulk flow on the coupling of antennas, and the bulk flow of an artificial electron beam.

“…A further study of the polar cap electric field was carried out by Heppner (1972c) using data of the OGO-6 satellite and by Caufman, Gurnett andFrank with Injun-5 data (Caufman andGurnett, 1971, 1972;Frank and Gurnett, 1971 ;Gurnett, 1972).…”

In this paper some theories and experimental data on the electric fields and currents in the ionosphere are reviewed. Electric fields originating in the polarization of the ionosphere as well as in local irregularities are considered. Special attention is paid to field-aligned currents as a regulator of the intensity and configuration of the ionospheric polarization field, the anomalous resistivity being one of the most important characteristics of the magnetospheric plasma. Present-day models of the magnetosphere and corresponding electric field generation mechanisms are discussed. Various models of the DP1 current system are considered and the main characteristics that allow us to distinguish between them are listed. Experimental data on the ionospheric electric field are considered; a modified model of Silsbee and Vestine is shown to fit these data reasonably well.

“…The .electric field in the auroral ionosphere has been measured using several techniques -ExB drift of Barium ion clouds; balloon, rocket and satellite-borne double-probes and ground-based incoherent scatter radars (e.g. Foppl et al, 1968;Mozer and Bruston, 1967;Cauffman and Gurnett, 1972;and Doupnik et al, 1972). These measurements have indicated generally northward electric fields in the afternoon and evening sectors and generally southward electric fields in the morning sector of the auroral zone.…”

The region of plasma flow and electric field reversal in the late evening auroral oval was observed simultaneously by auroral radar and by rocket. A strong, 30 ‐ 50 mV/m, northward electric field was measured in the southern part of the observing region and a strong southward field in the northern part. In the middle, rocket measurements showed a weak field that rotated from north, through east, to south. In this region, no radar auroral irregularities were observed when the electric field was less than ∼ 20 mV/m.
