Abstract : A direct method for determining real height from virtual height data has been applied to two ionograms from data recorded at Boulder, Colorado and Garchy, France. The initial height was obtained by a modification of the one-start procedure of Howe and McKinnis. The real height results obtained from the two ionograms were in good agreement with previously-reported accurate numerical calculations. To provide a simpler procedure for performing the required integration and thus make the present method more rapid and convenient, the virtual height data have been modeled in terms of polynomial governed by a single parameter. The parameter was determined by comparison of the model with the data. The results using the model were in good agreement with those obtained by direct use of the data. The present method affords a simple and convenient means of obtaining real height from virtual height data, within the accuracy of the experimental data. (Author)
