Analysis of Nuclear Propagation Effects Utilizing Wideband Satellite Data.

Abstract

Previous analyses of the Wideband Satellite data have emphasized the scale-size regime between 500 m and several tens of kilometers. In this report we describe the results of a detailed analysis of the auroral and equatorial total electron content (TEC) structure associated with the various scintillation phenomena. A nighttime equatorial anomaly was a priminent feature in the equatorial data, particularly as the solar cycle maximum approached. In the auroral data we found that an enhanced F region is the primary contributor to steep latitudinal TEC gradients. Because recent data have shown an abrupt steepening of the irregularity spectral density function near 500 m, a careful analysis of the mutual coherence function was performed to see if this feature could be detected in the Wideband scintillation data. The analysis did indeed reveal such a feature, which is evidently a permanent characteristic of the most severely disturbed equatorial irregularity continuum. (Author)
