Cluster observations of a field aligned current at the dawn flank of a bursty bulk flow
(Peer reviewed; Journal article, 2007-06-29)This article describes observations of a bursty bulk flow (BBF) in the outer central plasma sheet. The observations are made with the Cluster satellites, located approximately 19RE downtail, close to the midnight sector ... -
The Hall current system revealed as a statistical significant pattern during fast flows
(Peer reviewed; Journal article, 2008-11-05)We have examined the dawn-dusk component of the magnetic field, BY , in the night side current sheet during fast flows in the neutral sheet. 237 h of Cluster data from the plasma sheet between 2 August 2002 and 2 October ... -
Mesoscale ionospheric plasma irregularities and scintillation over Svalbard
(Doctoral thesis, 2016-10-21)This thesis investigates how navigation signals are compromised by ionospheric plasma irregularities in the auroral and polar ionosphere over Svalbard. In 2013, four multiconstellation global navigation satellite system ... -
Scintillation and irregularities from the nightside part of a Sun-aligned polar cap arc
(Peer reviewed; Journal article, 2016-06-18)In this paper we study the presence of irregularities and scintillation in relation to the nightside part of a long-lived, Sun-aligned transpolar arc on 15 January 2015. The arc was observed in DMSP UV and particle data ... -
Severe and localized GNSS scintillation at the poleward edge of the nightside auroral oval during intense substorm aurora
(Peer reviewed; Journal article, 2015-12)In this paper we study how GPS, GLONASS, and Galileo navigation signals are compromised by strong irregularities causing severe phase scintillation (σϕ>1) in the nightside high-latitude ionosphere during a substorm on 3 ...
