Enhancing the ISIS‐I Topside Digital Ionogram Database
Original language description
Selected original analog telemetry tapes from three of the topside-sounder satellites of the International Satellites for Ionospheric Studies (ISIS) program, namely Alouette 2, ISIS I, and ISIS II, were used in an earlier project to produce more than 1/2 million digital topside ionograms: the resulting digital topside ionograms from ISIS II were used to produce more than 86,000 globally distributed vertical topside ionospheric electron density profiles N-e(h) that cover a time span of more than a solar cycle. These N-e(h) were produced using the Topside Ionogram Scaler with True height algorithm auto-scaling software. Before attempting to automatically process Alouette-2 or ISIS-I ionograms, a data-enhancement project was initiated so as to increase the number of ionograms suitable for manual scaling and to increase the auto-processing success rate. These enhancements were mainly to correct problems that often occurred during the analog-to-digital conversion of the original telemetry tapes. Here we illustrate the improvements made to the ISIS-I digital topside ionograms and compare N-e values at the satellite altitude and N-e(h) profiles, based on the manual scaling of selected ionograms, to both the auto-scaled values and the predictions of the International Reference Ionosphere 2016 model. The results indicate the need to improve the available auto-processing software for the new ISIS-I digital ionograms and that International Reference Ionosphere 2016 predicts midlatitude winter topside N-e values that are too high in the late morning and at noon but too low in the early morning. n
