Some effects in the upper atmosphere during geomagnetic storms
(Elsevier, 2011-03)
This paper examines the response of the high latitude ionosphere- thermosphere system during two intense geomagnetic storms. For that, data taken by instruments on board Dynamic Explorer 2 taken at heights of the F2-layer ...
Positive and negative ionospheric storms occurring during the 15 May 2005 geomagnetic superstorm
(American Geophysical Union, 2015-08-10)
This study focuses on the 15 May 2005 geomagnetic superstorm and aims to investigate the global variation of positive and negative storm phases and their development. Observations are provided by a series of global total ...
The August 2011 URSI World Day campaign: Initial results
(Elsevier, 2015-11)
During a 10-day URSI World Day observational campaign beginning on August 1, 2011, an isolated, major geomagnetic storm occurred. On August 5, Kp reached values of 8− and Dst dropped to −113 nT. The occurrence of this ...
Ionospheric and thermospheric variations associated with prompt penetration electric fields
(American Geophysical Union, 2012-08-10)
This paper presents a comprehensive modeling investigation of ionospheric and thermospheric variations during a prompt penetration electric field (PPEF) event that took place on 9 November 2004, using the Thermosphere‐Io ...
Upper atmosphere perturbations at subauroral latitudes during an intense geomagnetic stormPerturbaciones en la atmósfera superior en latitudes subaurorales durante tormentas geomagnéticas intensas
(Universidad Nacional Autónoma de México. Instituto de Geofísica, 2004-12)
Neutral gas density data (molecular nitrogen N2 and atomic oxygen O) between 310 and 330 km of altitude obtained by the Dynamic Explorer 2 satellite and ground-based foF2 data obtained with ionosondes were used to examine ...
Thermosphere-Ionosphere response at middle and high latitudes during perturbed conditions: A case study
(Elsevier, 2008-12)
Neutral gas composition and ionospheric measurements taken by the Dynamic Explorer 2 satellite at F2-region heights (280–300 km) during an intense geomagnetic storm (peak Dst=−187 nT) were used to analyze the role of some ...
Behavior of the Total Electron Content over the Arctic and Antarctic sectors during several intense geomagnetic storms
(KeAi Communications, 2019-01)
In this paper, the behavior of TEC at three stations located in the Arctic and Antarctic sectors during some intense geomagnetic storms in the period 2012–2016 is analyzed. The results show the opposite storm effects in ...
Ionosphere variability during the 2009 SSW: Influence of the lunar semidiurnal tide and mechanisms producing electron density variability
(American Geophysical Union, 2014-04-23)
To investigate ionosphere variability during the 2009 sudden stratosphere warming (SSW), we present simulation results that combine the Whole Atmosphere Community Climate Model Extended version and the thermosphere-ionos ...
