Ionospheric variability at low latitude station: Hainan, China

Variability of equatorial ionospheric electron density at fixed heights below the F2 peak

“…Most of these studies are usually on peak electron density parameters e.g. Forbes et al (2000), Rishbeth and Mendillo (2001), Kouris and Fotiadis (2002), Rawer et al (2003), Sethi et al (2003), Bilitza et al (2004), Zhang et al (2004), Gordienko et al (2005), Lee and Reinisch (2006) and Dabas et al (2006). Only a few studies have been conducted on variability at various heights below the F2 peak.…”

Solar cycle variation of the monthly median foF2 at Chongqing station, China

“…The ionosphere experiences variations due to the influence of the solar and geomagnetic activities as well as other sources (Forbes et al, 2000;Zhang et al, 2004). For the same sunspot number, foF2 may show different values during the rise and fall of the cycle (Rao and Rao, 1969).…”

Variability of foF2 for an equatorial station and comparison with the foF2 maps in IRI model

“…Studies on variability vary from those that analyze specific parameters on a large geographical area, to those that are limited to a few stations or to one station. Such studies for example include those of Kouris et al (1998), Gulyaeva et al (1998), Leitinger and Hochegger (1999), Gulyaeva and Mahajan (2001), Rishbeth and Mendillo (2001), Kouris and Fotiadis (2002), Rawer et al (2003), Sethi et al (2003), Zhang et al (2004), and Gordienko et al (2005).…”
