данные описание

minimum virtual height of the ordinary wave trace for the highest stable stratification in the F region

minimum virtual height of the ordinary wave F trace (presumably, minimum height of Fl layer in daytime; in nighttime =h'F;)

the minimum virtual height of the trace used to give foEs (hourly h’E data)

minimum virtual height of the normal E layer (hourly h’E data)

ordinary wave critical frequency from the highest stratification in the F region (hourly foF2 data)

the ordinary wave Fl critical frequency (hourly foF1 data)

the ordinary wave top frequency corresponding to the highest frequency at which a mainly continuous Es trace is observed (hourly foEs data)

the critical frequency of the E layer (hourly foE data)

the lowest frequency at which echo traces are observed on the ionogram (hourly fmin data)

the lowest ordinary wave frequency at which the Es layer begins to become transparent (hourly fbEs data)

F2 layer’s M factor (the ratio of the maximum usable frequency divided by the critical frequency)
