Source effects in mid-latitude geomagnetic transfer functions

Mid-latitude Vertical Transmission of Geomagnetic Micropulsations through the Ionosphere

Subionospheric VLF measurements of the effects of geomagnetic storms on the mid-latitude D-region

We examine the effects on the mid-latitude D-region of two geomagnetic storms, the "Halloween storm" of late October 2003 and the 07 April 2000 storm, by means of the associated perturbations of several subionospheric VLF/LF signals propagating in both the northern and southern hemispheres. We use VLF/LF nighttime data from the Holographic Array for Ionospheric/Lightning Research (HAIL), locate...

Application of Theground-based Direction Finding Techniquesto the Vlf Wave Transmittedat Geomagnetic Conjugate Point in Mid-latitude

The multiple signal classification (MUSIC) method and the wave distribution function (WDF) method are applied to the artificial VLF wave propagation from Khabarovsk through the magnetospheric duct to the conjugate point Ceduna (L = 1.8). The estimated arriving direction and the wave energy indicates that the location of the termination of the magnetospheric duct fluctuates related to the geomag...

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Reverse domain-filling trajectory calculations have been performed for to calculate the spreading of ozone depleted air from the polar vortex to midlatitudes in spring. We find that for these years with massive Arctic o...

Trans - ionospheric GPS signal delay gradients observed over mid - latitude Europe during the geomagnetic storms of October - November 2003

Ionospheric disturbances are known to have adverse effects on the satellite-based communication and navigation. One particular type of ionospheric effects, observed during major geomagnetic storms and threatening the integrity performance of both ground-based and space-based GNSS augmentation systems, is the sharp increase/decrease in the ionospheric delay that propagates in horizontal directio...
