The Atmospheric Potential Gradient near the Surface of the Captive Balloon

Abstract

The atmospheric potential gradient near the surface of the captive balloon was measured at various heights from the earth's surface in different meteorological conditions. The bamboo-rod was erected on the surface of the balloon and Polonium-collector was attached to this rod. The lead wire connected the collector and the self-recording electrometer was fastened to the moorings. The potential gradient near the surface of the balloon is so much greater as the height of the balloon increases. When the balloon penetrates the haze-layer, the potential increases with height and reaches the maximum value and then decreases to the normal value with height.
