AURORAL ZONE IONOSPHERIC RESEARCH.

Abstract

The research was carried out with emphasis on Faraday rotation and scintillation phenomenon. It was found from Faraday rotation studies that the direction of the horizontal component of the geomagnetic field in the F-region differs by about 8 degrees from that at ground level. Increases of the rate of Faraday rotation observed in the auroral zone were explained in terms of large horizontal variations of the total electron content. It was found that the amplitude of these variations is about one order of magnitude larger than those observed at middle latitudes. Naturally occurring electromagnetic radiation in the audio-frequency range was also studied. The results obtained are to some extent compared with similiar measurements at Sagamore Hill, Mass., USA carried out during the same period. Several emission bands, which are quite distinct from the normal background-signals and are obtained as strong enhancements in portions of the spectrum, have been recorded. (Author)
