Atmospheric electricity

Abstract

During the period covered by this report (1967 through 1970), there was an increase in research activity which in part was a consequence of the general scientific development, but which in part was also triggered by the Montreux Conference in 1963 [Coroniti, 1965]. Several particular events had a stimulating effect on the amount of research, although it remains to be seen how long this effect will last. These events include the first intensification interval of the ten-year program, the lightning incident at the launching of Apollo 12, the first specific discussion on atmospheric electricity by the Commission of Atmospheric Sciences (CAS) of the World Meteorogical Organization (WMO), and the intensive investigation of the atmospheric electricity effects during solar eclipses (eight experiments on the March 7, 1970, eclipse by many investigators). Papers on atmospheric electricity were presented at many scientific sessions and special international meetings were conducted at the Fourth International Conference on the Universal Aspects of Atmosphere Electricity, Tokyo, 1968 [Coroniti and Hughes, 1969], the General Scientific Assembly of the International Association on Geomagnetism and Aeronomy, Madrid, 1969 [Dolezalek, 1970], a conference of the WMO-CAS Working Group on Atmospheric Electricity, Leningrad, 1970 [Koenigsfeld, 1970], a conference on ions, aerosols, and radioactivity conducted by the Working Group IV of the Joint Committee on Atmospheric Electricity, Paris, 1970 (proceedings to be published in J. Aerosol Phys., 1970), and the Fourteenth General Assembly of the International Union of Geodesy and Geophysics, St. Gallen and Luzern, 1967. Within the United States the meetings of the American Geophysical Union and the American Meteorological Society were at several times the framework for extended discussions on atmospheric electricity. (See entries at beginning of the bibliography for publication of abstracts.) Such discussions have also occurred at many other conferences too numerous to list.
