Preparation of theoretical ionograms for Delhi and analysis of Delhi ionograms (C/sub 4/-recorder) with it, to study production rates (q/sub 0/), loss rates ( beta /sub 0/) and scale heights (H/sub 0/) in F/sub 1/-F/sub 2/ transition region

摘要

The basic points in the preparation of theoretical h'F curves (overlays) for the low latitude station at Delhi and the necessity of renaming them theoretical ionograms are summarized. Significant results regarding q/sub 0/, beta /sub 0/, H/sub 0/, T/sub 0/, and T/sub infinity / obtained as a result of analyzing the Delhi ionograms (C/sub 4/-recorder) around F/sub 1/-maximum are discussed. The theoretical ionograms are discussed and compared with results obtained using other techniques. It is concluded that these theoretical ionograms can be equated with the actual ionograms of ionospheric recorders and can be prepared for any station whose propagation constants are known or for any location where the installation of a ionospheric recorder is difficult.
