Analysis of Simultaneous Polar Fox II Backscatter and Ionospheric Sounding Data
Abstract
Backscatter data from the northward-looking POLAR FOX II radar were simultaneously taken with airborne and ground-based ionospheric soundings and optical data supplemented by satellite observations. The detailed ionization contour lines in the region from 0 to 2000 km north of POLAR FOX II, obtained for a period of about 2 hours before local midnight in December, explain why only a small range section of ground could be seen during this period. Aspect- sensitive direct backscatter echoes from field-aligned laminae both in the E- and F-layer were dominant and were found to be reflected from latitudes where vertical soundings show spread-E and -F. Those regions appear to be identical to the auroral E (night E) layer and 'plasma ring' F layer known to be associated with the auroral oval.
