Web13 apr. 2024 · Abstract. We report the investigation of the ionospheric response to the passage of an annular solar eclipse over Southeast Asia on 26 December 2024 using multiple sets of observations. Two ionosondes (one at Kototabang and another at Pontianak) were used to measure dynamical changes in the ionospheric layer during the … Web6 apr. 2016 · These parameters are manually scaled by experienced specialists every one hour. Time is Japanese Standard Time (JST), which is UTC+9 hours. Detailed explanation and interpretation of ionograms are found in "U.R.S.I. Handbook of Ionogram Interpretation and Reduction, Report UAG-23A (1972)."

Web17 nov. 2012 · An ionogram is a display of the data produced by the ionosonde. It is a graph of the virtual height of the ionosphere plotted against frequency. Ionograms are often converted into electron density profiles. Data from ionograms may be used to measure changes in the Earth's ionosphere due to space weather events.

Automatic scaling of F2-layer parameters from ionograms
WebThe invention discloses a vertical measurement ionogram reversion method based on an overlapping polynomial model. The method comprises the following steps: step A, preprocessing actually measured data; step B, based on a result of the preprocessing of the actually measured data, calculating an E-layer profile by use of the overlapping … WebThis PowerPoint presentation introduces ionogram scaling to people who are familiar with a mid-latitude ionograms, but who have not given much thought to the effort that is … WebThe ionogram reduction techniques in common use all assume that the soundings are vertical. This assumption, in general, does not introduce serious errors in the :eduction of ground-based soundings. For topside soundings, however, the assumption can lead to large errors in N(h) results.
