Summary of Airplane Electric Field Measurements as Part of Ionospheric Electric Field Mapping Investigation, Thompson, Manitoba (August 1978).

Abstract : Constant altitude measurements of the vertical electric field were made from an aircraft at about 10 km over periods of several hours in the vicinity of balloons drifting at constant altitudes making similar measurements at altitudes near 25 km. Comparison of the aircraft and balloon records will be used to verify the theory of mapping ionospheric electric fields downward into the atmosphere. (Author)
