Publisher's Synopsis
Excerpt from A Survey of Spread F
Spread-f, like sporadic E, is a familiar and sometimes frequent abnormality encountered in radio soundings of the ionosphere. It occurs at some time or other at every station although its form and frequency of occurrence differ widely. The existence of the phe nomenon which is now commonly termed spread-f has been known for more than twenty years. Booker and Wells (1938) were the first to give a detailed account of the diffuse or spread appearance of the F-layer echo on many Huancayo ionograms.
