Abstract. Lord Kelvin (William Thomson) made important contributions to the study of atmospheric electricity during a brief but productive period from 1859–1861. By 1859 Kelvin had recognised the need for "incessant recording" of atmospheric electrical parameters, and responded by inventing both the water dropper equaliser for measuring the atmospheric potential gradient (PG), and photographic data logging. The water dropper equaliser was widely adopted internationally and is still in use today…

Fair weather atmospheric electricity : its origin and applications

Abstract—An entirely electrostatic view of the earth upper atmosphere system, as understood for example, by Lord Kelvin, underwent a paradigm shift around 1900 with definitive observations of

Atmospheric Electricity in High Latitudes

Investigation into the problems of atmospheric electricity may be divided into two periods. The first period was devoted almost entirely to measurements of the normal potential gradient in the lower

The density of the ionosphere appears to follow the sunspot cycle of 11 years, and it is expected that the radio-engineer will find substantial differences in the wireless wave-lengths best suited for long-distance communication.
