Single‐Polynomial Analysis of Ionograms
Radio Science, 1969A new formulation of the single‐polynomial analysis is presented, in which the electron density profile is assumed to begin with a flat base at a height equal to the lowest measured virtual height. This formulation gives a more accurately defined profile with only a small number of points and agrees with the assumptions normally made. Near the critical

The analysis of night-time ionograms
Journal of Atmospheric and Terrestrial Physics, 1975Abstract The analysis of ionospheric h′(ƒ) records can give appreciable errors at night, when large amounts of ionisation may be present with plasma frequencies less than the minimum recorded frequency ƒ min . The errors depend on both the total amount of low-density ionisation, and on the ionisation gradient near ƒ min .

Frequency shift in ionogram gyrofrequency resonance
Proceedings of the IEEE, 1970Additional evidence is presented from Alouette II ionogram data for the observed frequency difference between the plasma resonance detected near the electron gyrofrequency f H and the ionospheric value of f H =2.8 MHz ċ gauss-1. The observed values of the electron gyrofrequency resonance are usually about one percent higher than the ionospheric values ...
