Sudden Heating of the Ionosphere in the Auroral Zone

Nature, 1964
SODIUM clouds were released from Nike-Apache rockets launched from Fort Churchill, Manitoba (geomagnetic latitude 68.5° N.), on the evenings of May 21 and 22, 1963.

Redistribution of Ionization in the Auroral and Equatorial Ionosphere

Radio Science, 1971
It is shown that the electric fields that can exist in the auroral and equatorial ionospheres should produce a convergent flow of metallic ions. It is suggested that this convergent flow of ions is responsible for some of the sporadic E with high ƒbEs observed in these regions.

Radio wave absorption in the auroral ionosphere

Journal of Geophysical Research, 1963
The temporal and spatial morphology of the aurorally associated ionospheric absorption of cosmic radio noise is described, using the results of an analysis of the riometer data collected in Alaska over a 5-yr period. The observed daytime and winter maximums of absorption are interpreted as reflecting the temporal variation of the bombardment of the ...

Auroral and ionospheric station at the University of Alaska

Eos, Transactions American Geophysical Union, 1936
The death of Professor Fuller has retarded the completion of the auroral work which was being carried on under a grant from the Rockefeller Foundation. Although we have undertaken no new photographic work in this field, we have devoted some time to the reduction of Professor Fuller's data, and have under construction charts for the graphical ...

Auroral Effects on the Ionospheric E-Layer

1965
In this chapter we shall discuss in more detail the disturbances of the ionospheric E-layer caused by the particles impinging upon the atmosphere during aurora. We know that particles produce the luminosity we observe, and it is also a well-known fact that there are produced a number of electrons and ions, i.e.

Auroral enhancement of ionospheric electron density

Journal of Atmospheric and Terrestrial Physics, 1970
Abstract A localized increase in ion density of the F -layer and topside ionosphere at 75–80° magnetic latitude around magnetic noon has been termed the polar peak . Results reported by a number of aeronomists suggest that this polar peak is produced by the same flux that is responsible for the dayside aurora.

Auroral pulsations from ionospheric winds

Journal of Geophysical Research: Space Physics, 1989
The possibility that auroral pulsations are due to oscillatory electrical circuits in the ionosphere that are driven by the negative resistance of jet stream winds is examined. For the condenser plates, the highly conducting surfaces above the edges of the jet stream are postulated.
