The atmospheric electric fog effect typical variations of the basic atmospheric electric elements about 1 hour before the formation and the dissipation of fog was discovered independently by several researchers between 1950 and 1960, and confirmed by a series of later investigations. However, all attempts to explain it ad hoc have failed, and a quantitative physical explanation yet remains to be given. Therefore, any new approach should be based on a critical view of the work done and instruments applied before attempting to outline anew program of experiments. The importance of this program for knowledge as well as for practical application lies in the possibility to forecast fog events, and even more in the hope to obtain more information on the physical processes of the formation and dissipation of fog and on related physical phenomena. After a definition of the problems and a survey of the observations concerned chapters I and II, a critical study of all possibilities for a physical explanation is made, to present the foundation for future experiments chapters III and IV. In chapters V through VII, a program for the investigations is sketched, the locality of the field experiment is discussed, and the first steps of this research work are proposed in detail. An extensive bibliography, partially categorized according to subject chapter VIII, provides the sources for the present study as well as for the future work chapter IX.
