Spatio-Temporal Evolution of Global Ionospheric Storm Drivers and Hemispherical Asymmetry During 17--18 March 2015 Geomagnetic Storm

The local, regional, and global morphology of the ionospheric response of the March 2015 geomagnetic storm has been investigated by different studies. However, the spatio-temporal evolution of the drivers of the global ionospheric response to this storm has not yet been investigated, using multi-data sources, in detail. Therefore, in this study drivers of the ionospheric response to the March 17–18, 2015 storm are investigated. Spatial and temporal variations of deposition of solar wind energy are found to be the cause for ...

Equatorial and low-latitude ionospheric TEC response to CIR-driven geomagnetic storms at different longitude sectors

In this study the response of ionospheric F-region to 18–21 September 2014, 19–24 January 2016, and 07–10 March 2016 CIR-driven storms in the equatorial and low-latitude region of

The response of the ionosphere to intense geomagnetic storms in 2012 using GPS-TEC data from East Africa longitudinal sector

The response of the ionosphere to intense magnetic storms has been studied using total electron content (TEC). TEC data recorded by a series of GPS receivers at a longitude\~35\textdegreeE\ covering a wide range of latitudes (32\textdegreeS\ to\ 68\textdegreeN, geographic) is analyzed to study spatio-temporal modifications of the vertical TEC (vTEC) during storms on 07 and 09 March 2012 and on 14 July 2012. We have observed main phase positive response at equatorial ionization anomaly (EIA) crests and mid l ...
