Direct measurements of the atmospheric conduction current
Journal of Geophysical Research: Oceans, 1978A new method of measuring the atmospheric conduction current above the ground has been employed to obtain data for 12 weeks during the first half of 1974. The instrument consists of a split aluminum sphere suspended by insulated wires to a wooden frame. The measuring electronics and the transmitter are enclosed within the spherical structure.

Electrical Conductivity of the Atmosphere over an Urban Location
Atmospheric and Oceanic Optics, 2021The simultaneous measurements of atmospheric electrical conductivity and meteorological parameters during 2015 over an urban location were carried out, and their variations are presented. During fair weather days, the variations in air conductivity show a pronounced diurnal trend with early morning hour maxima and afternoon minima.

The low electrical conductivity of Titan's lower atmosphere
Icarus, 2021Abstract Titan's near-surface atmosphere, with a relatively high density and with weak ion production by cosmic rays or other sources, likely has a lower electrical conductivity than the Earth's, possibly Some local enhancement of conductivity at the surface may occur due to radiocarbon in recent surface deposits, and a significant perturbation may

Interactions of the thunderstorm with a conducting atmosphere
Journal of Geophysical Research, 1969Vertical dipole charge configurations placed in an atmosphere where the conductivity increases exponentially with altitude have been calculated. The problem is divided into cases involving fast and slow time variations, so that quasi-stationary situations can be compared with the fast changes of lightning discharges.

Production of Artificial Conducting Regions in the Atmosphere
IEEE Transactions on Plasma Science, 2019There are a number of applications for artificial conducting regions at a convenient ionospheric height and electron density. As a convenient means to this end, we have proposed and explored the production of high-electron-density regions in the atmosphere in daytime by suspension of low work function dust, specifically Cs-coated bronze in the ...

THE AIRBORNE MEASUREMENT OF ATMOSPHERIC CONDUCTIVITY
Journal of Geophysical Research, 1958The simultaneous measurement of both polar conductivities from a P4Y airplane using two Gerdien-type condensers is described. An altitude distribution of conductivity representative of clear arctic air is presented. From this distribution, a columnar resistance of 6.0×1016 ohm-m2 is obtained by integration from the earth's surface to 6 km.

Atmospheric Environment (1967), 1975
Abstract Like the natural radioactivity, the polar conductivity of the air shows a pronounced diurnal variation: the records show a sharp peak in the early morning and a very flat minimum in the afternoon. The diurnal variation is most pronounced from late spring to early autumn, i.e.

Measurements of atmospheric electrical conductivity near the ground
Journal of Atmospheric and Terrestrial Physics, 1966Abstract Measurements of the positive and negative ionic conductivities close to the ground show that, at Durham, both conductivities decrease with height above the ground, in contrast to results of Hogg (1939) at Kew. The ratio of positive to negative conductivity and the alterations with height all decrease with increasing wind-speed.
