Abstract

An analysis of squares of noon median F2 layer critical frequencies for a 3-year period has been made in order to derive the latitude variation of the annual effect in the electron densities and its relation to average F21ayer ionization. The results indicate that the annual component varies with the latitude in a manner very nearly similar to that of the steady ionization R0 and that for a given value of Ro for any latitude. R1 which can be derived approximately from a linear relationship of the type Rl = 0.3 Ro-4.5. A similar analysis of 9-year data, for precise phase and amplitude of the annual component for a pair of stations yields a value of Rl which is of the same order of magnitude as Ro and which attains a maximum around the epoch of minimum sun-earth distance.
