We summarize here the current state of knowledge of solar cycle variations in the morphology of the Venus dayside and nightside ionospheres, and in the mechanisms for maintaining the nightside ionosphere. The solar cycle variability of the dayside ionosphere is well understood.

Ionospheric Analysis and Ionospheric Modeling
1975Abstract : A global ionospheric model of the ionosphere was developed which allows for the incorporation of hourly observations of ionospheric parameters. A polar ionospheric model for foF2 was developed which contains corrections to a median model which are characteristic of the polar region.

EXPERIENCE with high-frequency radio direction finding has suggested that some of the deviations from great-circle bearings observed on signals propagated by way of the ionosphere may be attributed to a tilting or wrinkling of the reflecting layer, particularly in the case of the F-layer.

FOR some ten years, at the Zi Ka Wei Observatory, in Shanghai, China, we have been using, with exceptional success, a new technique in our weather forecasting. This method is based on an as yet unexplained correlation between the usual ionosphere echoes (E, F and F 2) and the future movement or behaviour of the three main air masses, which make the ...
