Description

The results of observations over 3 1/2 solar-cycles of ionosonde parameters describing sporadic-E patches (E/sub s/) are given for two Southern Hemisphere stations. Analysis has revealed systematic changes in the occurrence probabilities of f/sub o/ E/sub s/ and f/sub b/ E/sub s/ changes that are independent of time of day or season. It is unlikely that observational effects can be entirely responsible for the trends, which suggest that major long-term changes may be occurring at E region heights
