“…[3 -9]. In addition to global and large-scale generators, local space charge on aerosols and/or microdroplets can produce significant disturbances in the electric field, thereby affecting the ratio of the components of the atmospheric electric current density [10,11]. Above the planetary boundary layer, the net vertical electric current density is the sum of the polar conduction current densities due to oppositely directed drift of positive and negative air ions in the electric field and diffusion currents acting against the ion concentration gradients [12].…”

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.
