Technical Possibilities and Limitations of the DPS-4D Type of Digisonde in Individual Meteor Detections

Original language description

During the peak days of the 2019 Leonids and Geminids (16-19 November and 10-16 December), two ionograms/minute and one Skymap/minute campaign measurements were carried out at the Sopron (47.63 degrees N, 16.72 degrees E) and Pruhonice (50.00 degrees N, 14.60 degrees E) Digisonde stations. The stations used frequencies between 1 and 17 MHz for the ionograms, and the Skymaps were made at 2.5 MHz. A temporary optical camera was also installed at Sopron with a lower brightness limit of +1 visual magnitude. The manual scaling of ionograms for November and December 2019 to study the behavior of the regular sporadic E layer was also completed. Although the distributions of the stations were similar, there were interesting differences despite the relative proximity of the stations. The optical measurements detected 88 meteors. A total of 376 meteor-induced traces were found on the Digisonde ionograms at a most probable amplitude (MPA) threshold of 4 dB and of these, 40 cases could be linked to reflections on the Skymaps, too. Of the 88 optical detections, 31 could be identified on the ionograms. The success of detections depends on the sensitivity of the instruments and the noise-filtering. Geometrically, meteors above 80 km and with an altitude angle of 40 degrees or higher can be detected using the Digisondes.
