Pk. Bhuyan et al., STATISTICAL DISTRIBUTION OF IEC AT MIDLATITUDE AND ITS APPLICATION TOEARTH-IONOSPHERE COMMUNICATION-SYSTEMS, Indian journal of radio & space physics, 22(3), 1993, pp. 205-206
The IEC data obtained from three midlatitude stations Tokyo (33.5-degr
ees-N, 138.7-degrees-E) and Osan (34.0-degrees-N, 127.0-degrees-E) in
the Pacific and Athens (34.5-degrees-N, 18.4-degrees-E) in the Mediter
ranean region, during solar maximum period January-December 1980 (R(z)
BAR = 154.6) have been statistically analysed so as to prepare a ready
-to-use reference for earth-ionosphere communication system prediction
s. A good correlation of DELTAIEC with IEC(max) shows that the latter
could be used as an indicator of depolarization of communication signa
