Excerpt from Researches on the Height Variation of the Atmospheric Electric Potential Gradient in the Lowest Layers of the Air: Inaugural Dissertation The problem of the height variation of the potential gradient of atmospheric electricity in the layers of the air close to the ground is a very interesting one. The need for researches with regard to this question has been emphasized by W. Thomson (Lord Kelvin), F. Exner, B. Chauveau, W. F. G. Swann, and others. Nevertheless only one fairly careful experimental investigation into the matter has been published. It was made by A. A. Daunderer, who observed the gradient at three different heights, viz. close to the ground and at a distance of 1 and 2 metres above it. Theoretic calculations of the variation of the potential gradient in the interval 0 - 10 metres have, however, been made by E. v. Schweidler, M. Behacker, W. F. G. Swann. All these authors have employed the method suggested by Sir J. J. Thomson of calculating the field between the surfaces of two condensers under certain given conditions of ionisation. A solution of this problem, in which the difference in specific velocity between positive and negative ions was taken into consideration, has been given by M. Behacker, who followed a treatment of the differential equation, which had been suggested by G. Mie. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
