چکیده
By using the data of GNSS (Global Navigation Satellite System) observation from Crustal Movement Observation Network China (CMONOC), ionospheric electron density (IED) distributions reconstructed by computerized tomography (CIT) technique are used to investigate storm effects over Wuhan region during 17 March and 22 June 2015 geomagnetic periods. F-region critical frequency (foF2) at ionosonde station shows an obvious decrease recovery phase St. Patrick’s Day storm. Moreover, tomographic results present that in begins 12:00 UT on main phase. Also, foF2 a long-lasting negative effect Electron chromatography presents evident day accordance with observation. These probably associated changes chemical composition, PPEF DDEF high latitudes.

Investigation of the effects of geomagnetic storms on ionospheric irregularities using the combination of ground-based GNSS and SWARM satellites
Geomagnetic storms are one of the main causes of ionospheric perturbations in different sizes, depending on their intensity, which could disturb radio signals passing through this medium. On September 6-12, 2017, the sudden storm commencement (SSC) was the most massive geomagnetic storm of the year due to the X9 solar flare caused by a coronal mass ejection (CME). IMF-Bz and Dst values increase...
متن کاملIonospheric redistribution during geomagnetic storms
[1]The abundance of plasma in the daytime ionosphere is often seen to grow greatly during geomagnetic storms. Recent reports suggest that the magnitude of the plasma density enhancement depends on the UT of storm onset. This possibility is investigated over a 7year period using global maps of ionospheric total electron content (TEC) produced at the Jet Propulsion Laboratory. The analysis confir...

متن کاملIonospheric f oF2 anomalies during some intense geomagnetic storms
The global evolutions of f oF2 anomalies were examined for three very intense geomagnetic storms, namely the Halloween events of October–November 2003 (Event X, 29–30 October 2003, Dst −401 nT; Event Y, 20–21 November 2003, Dst −472 nT), and the largest Dst storm (Event Z, 13–14 March 1989, Dst −589 nT). For Event X, troughs (negative storms) were clearly seen for high northern and southern lat...
متن کاملIonospheric F-region storms: unsolved problems
Befitting the venue of this meeting, we first investigate the polar ionosphere. The most pressing problem here is that no reliable description of this region is available, not even for undisturbed conditions. To improve on this situation we have investigated the properties of some of the more prominent anomalies observed in this region, including the heating effect below the magnetospheric cusp...
