Abstract : Oblique incidence ionospheric soundings originating at Puerto Rico, Norway and California have been recorded at Maynard, Massachusetts. The course of the F2 layer maximum observable frequencies for these paths are presented. In the case of the Puerto Rico path, the progress of the one-hop F2 layer junction frequency (JF) follows predictions closely, although the maximum observed frequency (MOF) departs appreciably from the JF in the summer months due to sporadic E, which frequently has a persistent character in that season. Preliminary results of relative amplitude measurements for the upper and lower rays of the Puerto Rico F2 returns are presented. (Author)
