VLF HISS AT SYOWA STATION, ANTARCTICA
1970-03-30 Analyzing the VLF hiss (or auroral hiss) record at Syowa Station (geomagnetic latitude -69.7°) , Antarctica, which induced the observation on polarization, incident angle and intensity, we have found the evidence that VLF hiss is right-handed, and elliptically polarized, wave (whistler mo...
