Ionospheric electron density

WebIn order to make a general study of ionospheric structure, this paper reconstructs the electron density distribution based on a modified two-dimensional computerized ionospheric tomography (CIT) technique, where the FR angles, rather than the total electron content (TEC), are regarded as the input. WebRocket ionosphere experiments give the relative delay of a pulsed signal as a function of rocket position. ... are analyzed for rocket ascent and descent for two frequencies, 4.05 and 4.87 Mc. The electron-density distribution from rocket descent data for both frequencies are in good agreement and show peaks at 106, 111, 117, and 128 km.
