“…The results of this simulation made it possible to put forward an assumption about the possibility of the formation of electrical stratification with several series-connected sections, in which the generators can operate in the opposite direction, partially compensating each other [19,20]. Estimates of the electromotive force based on the data collected during systematic ascents and descents of a tethered balloon with a measuring platform fall in the range of 5 -55 kV, which is consistent with those obtained earlier, but the localization of the charge separation region did not allow to assume that the generator was associated with convective mixing of space charge [21].…”

“…A winch-driven helium-filled balloon made of polyester fiber material was used for measuring aloft. The following devices were mounted on the original measuring platform: two electrostatic field mills, two Gerdien chamber type sensors of air polar conductivities, sensor of radon activity Radon Scout PMT, aerosol particle counter AEROTRAK 9306v2, barometric altimeter, GPS receiver, meteorological and telemetric sensors, autonomous controlling and data collection systems, and power supply [21]. The elevation of platform varied from 2 to 500 m depending on wind speed and research program.…”

This work presents the results of ground-based and tethered balloon observations of altitude profiles of the components of the atmospheric vertical electric current density. The magnitude of the conduction current density was observed in the range 0.2 - 2 pAm−2. The ratio of the negative to positive component of the conduction current density averaged 1.6 outside the layer, where their dependence on the height was noticeable. In the framework of developed numerical model with reasonable values of the parameters it is found that the ratio of the convection current density to the density of the total vertical atmospheric electric current in the atmospheric boundary layer mainly falls in the range 0.2 - 0.6 and tends to increase under strong convection and low electrical conductivity. An exponential parameterization of the dependence of the electromotive force on the ground-level electrical conductivity is proposed.
