300 KC/S SOUNDINGS OF THE NIGHTTIME E LAYER AND ORIGIN OF ECHO PATTERNS
Abstract
The 300 kc/s 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 el/cc 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)
