Abstract

Abstract

This paper presents a method for the reduction of the ionospheric profile by using ordinary traces. The height of the Flayer bottom is determined by Gulyaeva's empirical equation. The ionospheric valley between Eand Flayers is an equivalent slab layer. The true-height reduction of the Flayer is based on Budden's method. The results of the reduction are compared with the profiles provided by Herbert. The error of true height is generally less than ±10 km for the middle latitudes.
