Response of the Antarctic Ionosphere to Some Intense Geomagnetic Storms
(Bentham Open, 2017-05)
The effect of geomagnetic storms on the mid-high latitude F2 region is studied. For that, foF2 data from four Antarctic stations were analyzed during three intense magnetic storms occurred in high solar activity (years ...
Mid-latitude ionospheric effects of a great geomagnetic storm
(Elsevier, 2004-08)
On March 13, 1989 magnetic storm effects on the mid- and low-latitude ionosphere were investigated. For this, peak electron density of F2-layer (NmF2) data from four chains of ionospheric stations located in the geographic ...
Ionospheric response to the 3 August 2010 geomagnetic storm at mid and mid-high latitudes
(Elsevier, 2013-01)
The global ionospheric response to the geomagnetic storm occurred of 3 August 2010 is studied in terms of the ionospheric parameter foF2. Data from three longitudinal sectors (Asia/Pacific, Europe/Africa and America) ...
Ionospheric effects of an intense geomagnetic storm
(Springer, 2007-12)
An investigation of the response of the mid-high, mid and low latitude critical frequency foF2 to the geomagnetic storm of 15 July 2000 is made. Ground-based hourly foF2 values (proportional to square root of peak electron ...
Moderate geomagnetic storms and their ionospheric effects at middle and low latitudes
(Elsevier, 2011-08)
This paper reports the global response of the mid high and low latitude ionosphere in four longitudinal sectors to two moderate geomagnetic storms that occurred during 2007 (the more intense storms occurred that year). The ...
Low latitude storm time ionospheric electrodynamics
(Elsevier, 2002-04-30)
The response of the low latitude ionosphere to high latitude convection has long been the subject of considerable interest. Radar, ionosonde, magnetometer, and satellite measurements have been extensively used for studying ...
Relative effects of electric field and neutral wind on positive ionospheric storms
(SpringerOpen, 2009-05-14)
The paper studies the relative importance of penetrating eastward electric field (PEEF) and direct effects of equatorward neutral wind in leading to positive ionospheric storms at low-mid latitudes using observations and ...
Response of equatorial, low- and mid-latitude F-region in the American sector during the intense geomagnetic storm on 24–25 October 2011
(Elsevier, 2013-07)
In this paper, we present and discuss the response of the ionospheric F-region in the American sector during the intense geomagnetic storm which occurred on 24–25 October 2011. In this investigation ionospheric sounding ...
Observations of the April 2002 geomagnetic storm by the global network of incoherent scatter radars
(European Geosciences Union (EGU), 2005-01)
This paper describes the ionospheric response to a geomagnetic storm beginning on 17 April 2002. We present the measurements of ionospheric parameters in the F-region obtained by the network of eight incoherent scatter ...
