R. A. Greenwald,K. B. Baker,J. R. Dudeney,Michael Pinnock,T. B. Jones,E. C. Thomas,Jean-Paul Villain,Jean-Claude Cerisier,C. Senior,C. Hanuise,R. D. Hunsucker,George J. Sofko,James A. Koehler,Erling Nielsen,R. J. Pellinen,Anthony Walker,N. Saot,H. Yamagishi +17 more
TL;DR: The Dual Auroral Radar Network (DARN) is a global-scale network of HF and VHF radars capable of sensing backscatter from ionospheric irregularities in the E and F-regions of the high-latitude ionosphere as mentioned in this paper.
Journal ArticleDOI
Localized activation of the distant tail neutral line just prior to substorm onsets
Masakazu Watanabe,Michael Pinnock,Alan S. Rodger,Natsuo Sato,H. Yamagishi,A. Sessai Yukimatu,R. A. Greenwald,Jean-Paul Villain,Marc R. Hairston +8 more
TL;DR: In this paper, the authors found flow burst features in the nightside ionosphere that are thought to be the ionospheric signature of distant tail reconnection, observed to form just prior to substorm onsets.
Book ChapterDOI
CONJUGATE FEATURES OF AURORAS OBSERVED BY TV CAMERAS AND IMAGING RIOMETERS AT AURORAL ZONE AND POlAR CAP CONJUGATE-PAIR STATIONS
TL;DR: In this paper, geomagnetically conjugate point observations in northern and southern polar regions provide unique opportunities to study whether the symmetry of magnetospheric configuration is maintained, or breaks down at the time of auroral substorms.
Journal ArticleDOI
Characteristics of polar cap aurora
TL;DR: In this paper, the characteristics of extremely high-latitude dayside auroras were examined by using auroral TV data obtained at Godhavn, Greenland, and simultaneous DMSP particle data.
