ELF AND VLF EMISSIONS IN NORTHERN SCANDINAVIA.

Abstract

Naturally-occurring emissions in the ELF- and VLF-band were studied in Northern Scandinavia from June 1964 to August 1966. Both of physical and practical reasons this investigation has been divided into four subgroups, namely: (1) Measurements of different types of hydromagnetic emissions between DC and 6 cps. (2) Studies of the earth-ionosphere cavity resonance band in the frequency range 6 to 100 cps. (3) Investigation of the fine structure of the emission band centered at approximately 700 cps, as well as recordings of the natural electromagnetic spectrum between 1 and 10 kc/s. (4) Studies of the enhanced VLF- and LF-emissions at six discreate frequencies between 2.3 and 50 kc/s. The results are presented and discussed. (Author)
