E. J. Weber,J. A. Klobuchar,J. Buchau,Herbert C. Carlson,R. C. Livingston,O. de la Beaujardiere,M. A. McCready,J. G. Moore,G. Bishop +8 more
TL;DR: In this article, coordinated measurements of F region plasma patches were conducted on February 3/4, 1984, from Thule and Sondrestrom, Greenland, for the first time these patches were directly tracked flowing in the antisunward direction over distances of 3000 km from the center of the polar cap to the poleward edge of the auroral oval.
Journal ArticleDOI
Ionospheric structures in the polar cap: Their origin and relation to 250‐MHz scintillation
J. Buchau,E. J. Weber,David N. Anderson,Herbert C. Carlson,J. G. Moore,Bodo W. Reinisch,R. C. Livingston +6 more
TL;DR: In this article, an investigation of the polar cap ionosphere near the peak of the last solar cycle identified polar cap F layer arcs and ionization patches as unique features, and as sources of severe scintillations observed on 250-MHz satellite beacon signals.
Journal ArticleDOI
High frequency induced enhancements of the incoherent scatter spectrum at Arecibo
TL;DR: In this paper, a number of enhancements of the incoherent scatter spectrum excited by strong high frequency (HF) radio waves were observed during an ionospheric heating experiment in January at Arecibo, where significant time variations over scales of tens of µsec through hours were seen.
Journal ArticleDOI
Sharpening our thinking about polar cap ionospheric patch morphology, research, and mitigation techniques
TL;DR: In this paper, the polar cap patches are formed by transient magnetic reconnection events and the shears become the dominant plasma structuring mechanism until the initial magnetic tension force is relaxed.
Journal ArticleDOI
Observations of fluxes of suprathermal electrons accelerated by HF excited instabilities
TL;DR: In this paper, the most direct observations to date of suprathermal electrons were reported at Arecibo, transmitting about 140 kW of o-mode power at 7.63 MHz, near but below the ƒ0F2 (exciting strong plasma wave instabilities near an altitude of 285 km) nighttime plasma line intensities were observed to be enhanced by a factor of 10-100.
