Ionospheric conductivity

WebIonospheric electron density in the E region, and hence ionospheric conductivity, is significantly altered by precipitating particles from the magnetosphere. This has global impacts on the thermosphere–ionosphere because of the important role of conductivity on high-latitude Joule heating. WebConductivity of the Ionosphere W. G. BAKER & D. F.
