Localized increment and decrement in the total electron content of the ionosphere as a response to the April 20, 2018, geomagnetic storm
(Hindawi Limited, 2018)
A moderate geomagnetic storm occurred on April 20, 2018. Using vertical total electron content (VTEC) maps provided by the Center for Orbit Determination in Europe, ionospheric responses to the geomagnetic storm could be ...
Emergence of a localized total electron content enhancement during the severe geomagnetic storm of 8 September 2017
(Copernicus GmbH, 2019-03)
In this work, the results of the analysis on total electron content (TEC) data before, during and after the geomagnetic storm of 8 September 2017 are reported. One of the responses to geomagnetic storms due to the southern ...

Disturbances at F2-region heights of equatorial anomaly during geomagnetic storms
(Elsevier, 2003-12)
Neutral gas composition and ionospheric measurements taken by the Dynamic Explorer 2 satellite at F2-region heights during two geomagnetic storms are used to analyze the role of some possible physical mechanisms responsible ...
The equatorial electrojet during geomagnetic storms and substorms
(American Geophysical Union, 2015-02-16)
He climatology of the equatorial electrojet during periods of enhanced geomagnetic activity is examined using long‐term records of ground‐based magnetometers in the Indian and Peruvian regions. Equatorial electrojet ...
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 ...
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 ...
Evidence of Geomagnetic Storm Effects in the Lower Atmosphere: A Case Study
(Springer, 2010-01)
Disturbances produced by geomagnetic storms in the higher regions of the Earth's atmosphere, such as in the ionospheric F2 region and in the lower ionosphere, are relatively better known than those produced at lower ...
Peculiar features of the low‐latitude and midlatitude ionospheric response to the St. Patrick's Day geomagnetic storm of 17 March 2015
(American Geophysical Union, 2016-07-25)
The current study aims at investigating and identifying the ionospheric effects of the geomagnetic storm that occurred during 17–19 March 2015. Incidentally, with SYM‐H hitting a minimum of −232 nT, this was the strongest ...
Inclination of the geomagnetic field measured by an incoherent scatter technique
(American Geophysical Union, 1971-01-01)
A technique to measure the direction of the geomagnetic field by using incoherent scatter techniques is described. The technique has been used to measure the inclination of the magnetic field at the Jicamarca Radar Observatory ...
