Electron Density Profiles from Automatically Scaled Digital Ionograms. The Artist's Valley Solution.
Abstract
Electron density 'true height' profiles are calculated from automatically scaled Digisonde ionograms. The profile algorithm uses the modified polynomial fitting method separately for the E and the F region profile calculations. A new approach to considering the transition region between the E and F layers allows to determine the F profile with good accuracy from the ordinary echo trace. The total electron content between the peak of the E layer and the bottom of the F layer is estimated to account for the observed retardation as function of frequency on the F trace. No effort is made to find the valley shape since this is not possible from the O trace alone. The new algorithm is tested on some model ionograms. Keywords: Electron density; True height; Digital ionograms; Digisonde.
