From August 1958 through March 1959 Stanford Research Institute operated sferic monitoring stations at Fairbanks, Alaska, at Thule, Greenland, and at St. Johns, Newfoundland to record sferic 3- to 30-kc waveforms, direction of arrival, and rates of occurrence of sferics, and atmospheric noise levels from 12 to 30 kc. Large amounts of the above data have been recorded. Also, uniformly distributed samples of the data have been analyzed to determine sferic amplitude and direction-of-arrival distributions, sferic waveform types, sferic ELF content, sferic source locations in all portions of the Northern Hemisphere, and RMS atmospheric noise levels as functions of time of day and season. In addition, the application of the data collected to the better understanding of VLF propagation and of the influence of geophysical phenomena are discussed.
