BEHAVIOR PATTERNS IN THE E sub s LAYER IN THE AURORAL AND CIRCUMPOLAR REGIONS,

Abstract

The sporadic E layer is observed over all regions of the earth, but its form differs from place to place, and a classification of the Es layer, based on differences in the external appearance of recordings of reflections on ionograms, has been developed. Three primary classes of sporadic layers are differentiated: the flat Es layers (types l, c, h and f), which are usually semitransparent, resulting in partial reflection of radio waves; Es layers with group delay and magnetoionic splitting (E nocturnal and Es type r); and diffuse Es layers (types a, q and s). These primary types of Es layers are described, and the distribution by latitudes, as observed at various times of day, are presented graphically. Data are presented for latitudes of 60 deg and higher.
