AURORAL ZONE FARADAY ROTATION STUDIES,

Abstract

The analysis of 20 month's Faraday rotation observations made at Kiruna Geophysical Observatory was carried out with emphasis on special properties of the auroral zone F-region, especially the geomagnetic field and variations in the total electron content. It was found that the direction of the horizontal component of the geomagnetic field in the F-region differs by about 6 degrees from that extrapolated from the components at ground level. Increabes of the rate of Faraday rotation observed in auroral zone were explained in terms of large horizontal variations of the total electron content. The amplitude of these variations is about one order of magnitude larger than observed at middle latitudes. (Author)
