Journal ArticleDOI
Equatorial scintillation and systems support
Keith M. Groves,S. Basu,E. J. Weber,M. Smitham,H. Kuenzler,Cesar E. Valladares,R. Sheehan,E. MacKenzie,James A. Secan,P. Ning,W. J. McNeill,D. W. Moonan,M. J. Kendra +12 more
TL;DR: In this paper, the authors present the Scintillation network decision aid, which consists of two latitudinally dispersed stations, each of which uses spaced antenna scintillation receiving systems to monitor 250-MHz transmissions from two longitudinally separated geostationary satellites.
Journal ArticleDOI
Scintillations, plasma drifts, and neutral winds in the equatorial ionosphere after sunset
S. Basu,Erhan Kudeki,Su. Basu,Cesar E. Valladares,E. J. Weber,H. P. Zengingonul,Sumita Bhattacharyya,R. Sheehan,John W. Meriwether,Manfred A. Biondi,H. Kuenzler,J. Espinoza +11 more
TL;DR: An equatorial campaign was conducted during September 25 to October 7, 1994, to investigate the neutral and plasma dynamics in the equatorial ionosphere after sunset in relation to the day-to-day variability of the occurrence of equatorial spread F (ESF).
Journal ArticleDOI
Latitudinal extension of low-latitude scintillations measured with a network of GPS receivers
TL;DR: In this article, a case-study event was presented in which the latitudinal extension of GPS scintillations, the maximum latitude of TEC depletion detections, and the altitude extension of radar plumes were correlated with the location and extension of the equatorial anomaly.
Journal ArticleDOI
The multi‐instrumented studies of equatorial thermosphere aeronomy scintillation system: Climatology of zonal drifts
TL;DR: In this paper, the first year's drift and scintillation statistics have been presented as a function of local time, season and magnetic activity and compared with the statistics of ion drift published earlier from incoherent scatter radar observations.
Journal ArticleDOI
Characteristics of plasma structuring in the cusp/cleft region at Svalbard
S. Basu,E. J. Weber,Terence Bullett,M. J. Keskinen,E. MacKenzie,Patricia H. Doherty,R. Sheehan,H. Kuenzler,P. Ning,J. Bongiolatti +9 more
TL;DR: In this article, a study of the distribution and dynamics of mesoscale (tens of kilometers to tens of meters) electron density irregularities in the dayside auroral region was performed at Ny Alesund, Svalbard, by measuring the effects of these irregularities on the amplitude scintillation of 250-MHz transmissions from a quasi-stationary polar satellite as well as the amplitude and phase scintillations of 1.6-GHz signals from Global Positioning System (GPS) satellites.
