Studying the G condition occurrence in different latitudes under solar minimum: Observation and modeling
We analyzed the G condition occurrence, using data of ionospheric vertical sounding from stations Nbrilsk (69.4 degrees N, 88.1 degrees E), Irkutsk (52.5 degrees N, 104 degrees E) and.Hainan (18.3 degrees N, 109.3 degrees E) during the last extreme low solar activity period (2006-2009). In most case...
