Scintillation and loss of signal lock from poleward moving auroral forms in the cusp ionosphere
K. Oksavik, C. van der Meeren, D. A. Lorentzen +2
We present two examples from the cusp ionosphere over Svalbard,where poleward moving auroral forms (PMAFs) are causing significant phase scintillation in signals from navigation sa…
An extensive survey of dayside diffuse aurora based on optical observations at Yellow River Station
De-Sheng Han, Xiang-Cai Chen, Jian-Jun Liu +6
By using 7 years optical auroral observations obtained at Yellow River Station (magnetic latitude N) at Ny-Alesund, Svalbard, we performed the first extensi…
Severe and localized GNSS scintillation at the poleward edge of the nightside auroral oval during intense substorm aurora
Christer van der Meeren, Kjellmar Oksavik, Dag A. Lorentzen +2
In this paper we study how GPS, GLONASS, and Galileo navigation signals are compromised by strong irregularities causing severe phase scintillation ( > 1) in the ni…
Intensity asymmetries in the dusk sector of the poleward auroral oval due to IMF
J. P. Reistad, N. Østgaard, K. M. Laundal +5
In the exploration of global-scale features of the Earth's aurora, little attention has been given to the radial component of the Interplanetary Magnetic Field (IMF). This study in…
Estimation of cold plasma outflow during geomagnetic storms
S. Haaland, A. Eriksson, M. André +11
Low-energy ions of ionospheric origin constitute a significant contributor to the magnetospheric plasma population. Measuring cold ions is difficult though. Observations have to be…
