Hisslers: Quasi-periodic VLF noise forms observed at low latitude ground station Jammu (L = 1.17)

Abstract

This paper reports the observation of hisslers at a low latitude ground station Jammu (geomag. lat., 22°26′N), which are falling tone noises during the period of hiss activity and appear in minute-long sequences with average spacing between individual bursts of the order of 0.2 seconds and falling tones do not overlap intime. Generation and propagation mechanisms are briefly discussed. Copyright 2004 by the American Geophysical Union.
