| description | Variations in the D-region electron
concentration within the solar activity cycle are considered. It is demonstrated
that conclusions of various authors, who have analyzed various sets of
experimental data on [e], differ significantly. The most reliable seem to be the
conclusions based on analysis of the [e] measurements carried out by the Faraday
rotation method and on the theoretical concepts on the D-region photochemistry.
Possible QBO effects in the relation of [e] to solar activity are considered and
an assumption is made that such effects may be the reason for the aforementioned
disagreement in conclusions on the [e] relation to solar indices.<br><br><b>Key words.</b> Atmospheric composition and structure · Ion
