Upper Atmosphere Neutral Temperature Profiles in the Auroral Zone 1968-1970,
Abstract
Neutral temperatures have been measured above 120 km altitude from observations of the fluorescent emission of aluminium oxide and barium oxide clouds released from rockets launched at ESRANGE, Kiruna. The temperature observations showed a strong correlation with the C9 daily magnetic character rather than with the 3-hour Kp index. A small diurnal variation appeared from the data, the temperature at 165 km being on average 100K higher during evening twilight than morning twilight. No clear seasonal or longer term variations were apparent from the data. The results indicate a strong auroral zone enhancement of the heating associated with geomagnetic activity. (Author)
