ENVIRONMENTAL STUDIES FOR RADAR OPERATIONS IN THE AURORAL ZONE, PART I.
Abstract
The relation between VHF radio aurora and geomagnetic activity, as indicated by telluric current records, were investigated. VHF radio aurora, observed over Barrow, Alaska by a 41-mc radar at Kotzebue, Alaska, and telluric current activity at Barrow show a high correlation, particularly with respect to onsets of major activity. Slight or moderate activity usually gives some forewarning of intense activity, but some disturbances have extremely abrupt onsets of intense activity. The correlation is clearly highest for overhead and nearly overhead radio aurora and drops off for separations of 300 km and more. (Author)
