Open AccessConcurrent effects of Martian topography on the thermosphere and ionosphere at high northern latitudes
Martian topography modulated non-migrating tides play important roles in the upper atmosphere and thus in the ionosphere through their coupling, especially in their longitude variations. In this study, the neu...

Open AccessHow does ionospheric TEC vary if solar EUV irradiance continuously decreases?
It is an interesting topic how the ionosphere varies when solar extreme ultraviolet (EUV) irradiance decreases far below normal levels. When extrapolating the total electron content (TEC)-EUV relation, signifi...

Open AccessSolar activity effects of the ionosphere: A brief review
Solar radiation, which varies over multiple temporal scales, modulates remarkably the evolution of the ionosphere. The solar activity dependence of the ionosphere is a key and fundamental issue in ionospheric ...
