OBSERVATIONS OF WHISTLERS AND VLF EMISSIONS AT GODHAVN AND NARSSARSSUAQ, GREENLAND AND AT TROMSO, NORWAY IN 1963.
Abstract
VLF observations recorded during 1963 on magnetic tape at three stations, Godhavn and Narssarssuaq in Greenland and Tromso in Norway, have been treated statistically. The results show that whistlers propagate to Greenland from regions near the east and west coasts of the North American Continent. Good propagation conditions exist from the east coast of North America to Godhavn, 1000 km north of Narssarssuaq. Chorus below 2,0 kc/s occurs at all three stations at nearly the same geomagnetic time. Chorus in higher frequency ranges is observed only very rarely in Godhavn. The observations from Tromso and Narssarssuaq indicate that the time of the diurnal peak increases with latitude for these types of chorus. Earlier observations of correlation between hiss and other geophysical phenomena have been reconfirmed. (Author)
