On the Persistent Shape and Coherence of Pulsating Auroral Patches
Humberset, Beate Krøvel; Gjerløv, Jesper; Mann, Ian R.; Michell, Robert; Samara, Marilla (Peer reviewed; Journal article, 2018-05)The pulsating aurora covers a broad range of fluctuating shapes that are poorly characterized. The purpose of this paper is therefore to provide objective and quantitative measures of the extent to which pulsating auroral ... -
The Relationship Between Large Scale Thermospheric Density Enhancements and the Spatial Distribution of Poynting Flux
Billett, Daniel; Clausen, Lasse Boy Novock; Archer, William; McWilliams, Kathryn A.; Håland, Stein Egil; Reistad, Jone Peter; Burchill, J. K.; Patrick, M. R.; Humberset, Beate Krøvel; Anderson, B. J.; Perry, G. W. (Journal article; Peer reviewed, 2021)Large thermospheric neutral density enhancements in the cusp region have been examined for many years. The Challenging Minisatellite Payload (CHAMP) satellite for example has enabled many observations of the perturbation, ... -
Scale size-dependent characteristics of the magnetosphere-ionosphere system using auroral imaging
Humberset, Beate Krøvel (Doctoral thesis, 2017-10-06)The spectacular and breathtaking aurora dancing around on the night sky visualizes the fundamental behavior of complex processes in the near Earth space. The plethora of papers published over the last five decades have ... -
Scale size-dependent characteristics of the nightside aurora
Humberset, Beate Krøvel; Gjerløv, Jesper; Samara, Marilla; Michell, Robert (Peer reviewed; Journal article, 2017-02)We have determined the spatiotemporal characteristics of the magnetosphere-ionosphere (M-I) coupling using auroral imaging. Observations at fixed positions for an extended period of time are provided by a ground-based ... -
Temporal characteristics and energy deposition of pulsating auroral patches
Humberset, Beate Krøvel; Gjerløv, Jesper; Samara, Marilla; Michell, Robert; Mann, Ian R. (Peer reviewed; Journal article, 2016-07-23)We present a careful statistical analysis of pulsating aurora (PA) using all-sky green line (557.7 nm) images obtained at 3.3 Hz. Six well-defined individual PA patches are identified and extracted using a contouring ...
