Numerical modeling of ionospheric effects in the middle‐ and low‐latitude F region during geomagnetic storm sequence of 9–14 September 2005
Maxim Klimenko,Vladimir V. Klimenko,Konstantin Ratovsky,Larisa Petrovna Goncharenko,Yogeshwar Sahai,Paulo Roberto Fagundes,R. de Jesus,A. J. de Abreu,Artem M. Vesnin +8 more
TL;DR: In this paper, the Global Self-Consistent Model of the Thermosphere, Ionosphere and Protonosphere (GSM TIP) numerical simulations of the 9-14 September 2005 geomagnetic storm effects in the middle and low-latitude ionosphere are presented.
Journal ArticleDOI
The global thermospheric and ionospheric response to the 2008 minor sudden stratospheric warming event
Y.N. Korenkov,Vladimir V. Klimenko,Maxim Klimenko,Fedor Bessarab,N. A. Koren’kova,Konstantin Ratovsky,M. A. Chernigovskaya,A. A. Shcherbakov,Yogeshwar Sahai,Paulo Roberto Fagundes,R. de Jesus,A. J. de Abreu,P. Condor +12 more
TL;DR: In this paper, a study of the 2008 minor sudden stratospheric warming (SSW) event was performed using the Global Self-consistent Model of Thermosphere, Ionosphere, and Protonosphere (GSM TIP).
Journal ArticleDOI
Day-to-day variability of equatorial electrojet and its role on the day-to-day characteristics of the equatorial ionization anomaly over the Indian and Brazilian sectors
K. Venkatesh,Paulo Roberto Fagundes,D. S. V. V. D. Prasad,Clezio Marcos Denardini,A. J. de Abreu,R. de Jesus,R. de Jesus,Mauricio Gende +7 more
TL;DR: In this paper, the authors reported simultaneous variations of the equatorial electrojet (EEJ) and GPS-TEC over Indian and Brazilian sectors to understand the role of EEJ on the day-to-day characteristics of the EIA.
Journal ArticleDOI
Investigation of ionospheric response to two moderate geomagnetic storms using GPS–TEC measurements in the South American and African sectors during the ascending phase of solar cycle 24
A. J. de Abreu,Paulo Roberto Fagundes,Mauricio Gende,O. S. Bolaji,R. de Jesus,Claudio Antonio Brunini +5 more
TL;DR: In this article, the responses of the ionospheric F region using GPS-TEC measurements during two moderate geomagnetic storms at equatorial, low-, and mid-latitude regions over the South American and African sectors in May 2010, during the ascending phase of solar cycle 24, are investigated.
Journal ArticleDOI
