| Description |
The data sets are the ionospheric characteristic parameters from the Beijing observation station of Institute Geology and Geophysics Chinese Academy of Sciences (IGGCAS). The data sets are obtained from manual-scaled ionograms which are recorded with 1 hour step. These parameters include foF2 (F2 layer critical frequency), hmF2 (peak height of F2 layer), B0 (IRI thickness parameter), B1 (IRI profile shape parameter), hpF (minimum virtual height of F trace), foE (E layer critical frequency), fmin (minimum frequency of ionogram echoes), M3000F2 (MUF(3000)/foF2), foF1 (F1 layer critical frequency), foEs (Es layer critical frequency), and hpEs (minimum virtual height of Es trace). |
