Observations of Electron Density in the Polar Ionosphere Using the Swept Frequency Impedance Probe
Results of the electron number density obtained by the swept frequency impedance probe onboard the rockets launched at Syowa Station (69°00′S, 39°35′E) in the IMS period from 1977 to 1979 indicate that the ionization level of the polar ionosphere corresponds well to the precipitating particle flux....

Summary: | Results of the electron number density obtained by the swept frequency impedance probe onboard the rockets launched at Syowa Station (69°00′S, 39°35′E) in the IMS period from 1977 to 1979 indicate that the ionization level of the polar ionosphere corresponds well to the precipitating particle flux. In the active aurora, a distinct stepwise structure 2∿3km in width across the magnetic field line corresponding to the edge of the auroral arc has been observed. The small-scale ionospheric structures with characteristic length of several kilometers are frequently observed as one of the characteristics of the auroral ionosphere. |
