Abstract:

The 300 kcs group height recordings, obtained at The Pennsylvania State University, frequently show complex echo patterns. An attempt is made to deduce a model of the electron density - height profile below the nighttime F layer, based primarily on these records. The model consists essentially, of a thin ledge of ionization, of the order of 10,000 elcc and probably of meteoric origin, at the 95-100 km level and a regular retarding type E layer with its maximum around or above 120 km. The model is found to be consistent with data concerning this region obtained from other sources. Author
