Effects of a major storm on GPS amplitude scintillations and phase fluctuations at Wuhan in China

Effects observed in the ionospheric F-region in the South American sector during the intense geomagnetic storm of 14 December 2006

“…On the other hand, numerous investigations present both observational (e.g., Lee et al, 2002Lee et al, , 2004Sastri et al, 2002;Yizengaw et al, 2004;Xu et al, 2007;Lei et al, 2008a) andmodeling (e.g., Fuller-Rowell et al, 2002) results. In addition, some investigators have presented the results of geomagnetic storms at equatorial and low latitudes (e.g., Sahai et al, 2005;Zhao et al, 2005Zhao et al, , 2008.…”

A study of GPS ionospheric scintillations observed at Shenzhen

“…However, the ionospheric observation network is unevenly distributed across Sanya, Hainan, Guilin, Guangzhou, Shenzhen, Wuhan, etc. Previous researchers Xu et al, 2007;Li et al, 2008;Shang et al, 2008;Zou and Wang, 2009;Zou, 2011;Deng et al, 2013;etc. ) have studied the morphology of GPS ionospheric scintillations in the low latitude regions of China.…”

“…Shang et al (2008) (Zou and Wang, 2009;Zou, 2011). The effects of a major storm on GPS amplitude scintillations and phase fluctuations at the Wuhan (114.36°E, 30.53°N) station have been investigated by Xu et al (2007).…”

Effects of geomagnetic storm on GPS ionospheric scintillations at Sanya

“…Recently, the GPS ionospheric scintillations at a low-middle latitude station Wuhan in China during storms were studied (Li et al, 2006;Xu et al, 2006Xu et al, , 2007. In the present study, GPS scintillation/TEC measurements at Sanya (18.31N, 109.51E), Digisonde and DMSP plasma density data from other longitude sectors are utilized to study the effects of geomagnetic storms on equatorial ionospheric scintillations during the low scintillation occurrence season (for station Sanya, the GPS ionospheric scintillations mainly occur during equinoctial months (3,4,9,10), and are rarely observed at solstice).…”
