Analysis of ~21.5 d Period in Ionospheric and Solar Indices during 2011

By using Fourier transform, the spectrum of total electron content(TEC) data, relative sunspot number(RSSN), solar extreme ultraviolet(EUV) flux in 0.1~50 nm and 26~34 nm were performed to study the ~27 d period in solar-terrestrial environment. A~21.5 d period was found in TEC and solar indices, wh...
