Study on Factors Influencing the Ionospheric Conductivity

The ionospheric conductivity is an important parameter to describe the state of the ionosphere. There is a certain distribution law of the conductivity with the change of solar local time, latitudes and altitudes. In addition, some physical factors have direct effects on ionospheric conductivities. How these elements, such as solar activities, the geomagnetic index, electron temperature and electron density, influence it has been studied in this thesis, which will provide theoretical foundations and ideas for changing ionospheric conductivities manually.
