TEC, Periodograms and Period power of TEC, foF2 and hmF2 in the East-Asian sector from 2009 to 2020

The TEC, periodograms and period power of TEC, foF2 and hmF2 are calculated based on the Lomb-Scargle (L-S) periodgrams, Morlet wavelet spectral analysis and least-square fitting method. The TEC were derived from a chain of GNSS observation stations obtained from the Crustal Movement Observation Network of China (via e-mail to yglyang@cma.gov. cn) and IGS (http://sopac-csrc.ucsd.edu/). The foF2 and hmF2 were provided by the Beijing National Observatory of Space Environment and the Heilongjiang Mohe National Observatory of Geophysics (IGGCAS) via the Geophysics Center, National Earth System Science Data Center (http://wdc.geophys.ac.cn).
