Journal ArticleDOI
IRI-2007 model overestimates electron density during the 23/24 solar minimum
Hermann Lühr,Chao Xiong +1 more
TL;DR: In this paper, the authors compare electron density predictions of the International Reference Ionosphere (IRI-2007) model with in-situ measurements of the satellites CHAMP and GRACE for the years 2000-2009.
Journal ArticleDOI
Comparing plasma bubble occurrence rates at CHAMP and GRACE altitudes during high and low solar activity
TL;DR: In this paper, the authors focus on the equatorial plasma bubbles (EPBs) and show that EPBs form regions of depleted plasma along geomagnetic fluxtubes in regions of high occurrence rates.
Journal ArticleDOI
The Swarm satellite loss of GPS signal and its relation to ionospheric plasma irregularities
TL;DR: In this article, conditions for loss of GPS signals observed by the Swarm satellites during a 2-year period, from December 2013 to November 2015, were investigated, and the authors concluded that both lower electron density gradients and appropriate GPS receiver settings reduce the probability of GPS signal loss.
Journal ArticleDOI
Scale analysis of equatorial plasma irregularities derived from Swarm constellation
Chao Xiong,Claudia Stolle,Hermann Lühr,Jaeheung Park,Bela G. Fejer,Guram Kervalishvili,Guram Kervalishvili +6 more
TL;DR: In this article, the scale sizes of equatorial plasma irregularities (EPIs) were investigated using measurements from the Swarm satellites during its early mission and final constellation phases, and they found that with longitudinal separation between Swarm satellites larger than 0.4°, no significant correlation was found any more.
Journal ArticleDOI
Global features of the disturbance winds during storm time deduced from CHAMP observations
TL;DR: In this article, the authors used the CHAMP zonal wind observations from 2001 to 2005 to investigate the global features of the disturbance winds during magnetically disturbed periods, and they showed that the disturbance zonal winds are mainly westward, which increases with magnetic activity and latitude.
