A large array of experimental data from observations of ionospheric stations located in different regions of the world is used to consider the variations in the height of the F2-layer maximum during ionospheric disturbances of solar and magnetospheri

A large array of experimental data from observations of ionospheric vertical sounding stations located in different regions of the Earth has been used to study the features of long-term (1948–2019) time series of relative variations in the critical

The features of a time series of variations in the critical frequencies of the ionospheric F2 layer have been studied out based on a large file of experimental data. The stationarity of the δfoF2 samples and relative variations in the critical frequ

The paper focuses on the behavior of relative variations in the critical frequency of the F2 layer of the ionosphere δfoF2 in magnetically conjugate regions under quiet and disturbed conditions. Comparison of changes in δfoF2 over time shows that t

The temporal and spatial correlation of variations in the F2-layer critical frequency in various solar and geophysical conditions are considered based on a large array of experimental data. The possible extrapolation of ionospheric observational data

An adequate statistical method should be developed in order to predict probabilistically the range of ionospheric parameters. This problem is solved in this paper. The time series of the critical frequency of the layer F2−foF2(t) were subjected to

Heliobiological studies, although recently very active, have failed to provide a full understanding of the Sun–biosphere interaction mechanisms. This is because the forecasts of bio tropic effects of the active Sun, like geophysical forecasts, are
