Article

Summary

A new parameter-equivalent electron density (Nae)—has been introduced for evaluating the ionospheric condition inD region and the quantitative relations for its determination has been deduced. The new parameter is a function of the absorption and can be determined from a measurement point by a single frequency either by vertical incidence sounding or by registering the field strength for CW transmitter in a frequency range of 0.6–3 mc/s. The equivalent electron density presents a more objective information about the physical condition ofD region in comparison with the absorption itself and proves to be a suitable parameter for the study of the time variations of the ionisation conditions ofD region.
