Measurements of both polar conductivities, the electric field, mobility, density of small ions, and other related atmospheric variables were made from an airplane between 30 m and 6 km on two different series of flights separated by six years. Twenty-two soundings made in 1955-56 show that the general electrical characteristics can be classified by geographical regions. The variation of conductivity with altitude in the Arctic is shown to agree well with theory, if the value of mobility obtained in a 1962 series is used. A comparison of the two series indicates that the conductivity above the exchange layer and the mechanism by which the atmospheric potential is maintained was nearly the same, on the average, during both series of measurements.
