Abstract :
The results of a statistical investigation of the variation of E-region critical frequency f0E with solar activity, solar zenith angle and season, are synthesised to obtain a describing function of f0E in terms of geographic latitude, solar zenith angle and 10°7 cm solar radio-noise flux, for the design of ionospheric transmission paths. The reliability of the f0E expression is assessed by comparing predicted and observed values at various stations, and the standard error of estimate is determined.
