Long-Term Changes and Trends in the F2 Layer Critical Frequency over Alma-Ata (Kazakhstan)
The long-term variability and trends in the F2 layer critical frequency variations over Alma-Ata [43.25 N, 77.92 E] for the period 07.1957–04.2018 are studied using near-midday, near-midnight, and hourly median foF2 values. It is shown that the foF2 and solar activity index F10.7 display regular 11-...
