The Mahali Global Positioning System (GPS) array (9 receivers, 15鈥 30km baseline distance) in central Alaska has probed auroral structures in a field-aligned direction during a geomagnetic substorm on 7 October 2015. We present results from a collaborative study of GPS phase scintillation, ...
Field-aligned (Birkeland) currents 来自 Semantic Scholar 喜欢 0 阅读量: 15 作者: TA Potemra 摘要: Following earlier suggestions of Edmond Halley and Anders Celsius for the "magnetic behavior" of auroral phenomena, Kristian Birkeland discovered in his polar expeditions of 1902–03 that large-scale...
A comparison of the occurrences of "constant height" sporadic- E ( E sc) echoes and field-aligned ( E sφ) echoes from the E-region showed that at certain times of the year at least, there was a significant probability of their simultaneous occurrence. The probability was even more signif...
Chapter 8 ESA Field-Aligned Currents—Methodology Inter-comparison Exercise Lorenzo Trenchi and The FAC-MICE Team Abstract Various ESA projects and several proposals to first Swarm DISC Call for Ideas (May 2016) suggested possible evolution for the current Swarm Level 2 FAC products, and the ...
During the Sporadic E Experiment over Kyushu 2 (SEEK-2) campaign, field-aligned irregularities (FAIs) associated with midlatitude sporadic-E (E_s) layers were observed with two backscatter radars, the Lower Thermosphere Profiler Radar (LTPR) and the Frequency Agile Radar (FAR), which were ...

F1-region echoes from field-aligned ionization A statistical analysis of records obtained at Brisbane during August-December 1961, indicated that, at least on some occasions, direct backscatter echoes were observed from the F1-region. Detailed study of a typical set of records substa... GL Goodwin...
Radio propagation along magnetic field-aligned sheets of lonization observed by the Alouette Topside Sounder The following models proposed for long-delay echoes (LDE) are discussed: (1) radio waves of frequency less than about 4 MHz can become trapped in magnetic field-aligned ionization ducts with...

field lines. The existence of such field-aligned currents was widely disputed because it was not possible to unambiguously distinguish between current systems that are field aligned (Birkeland, 1908) and those which are completely ionospheric (Vestine and Chapman, 1938) only from a study of ...
