- PublicationOpen AccessApplication of Autoscala to ionograms recorded by the AIS-Parus ionosonde(2010-05)
; ; ; ;Krasheninnikov, I.; Pushkov InstituteofTerrestrialMagnetism,IonosphereandRadiowavePropagation,Russia ;Pezzopane, M.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia ;Scotto, C.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia; ; Autoscala was applied to ionograms recorded by the digital AIS-Parus ionosonde, built at the Pushkov Institute of Terrestrial Magnetism,Ionosphere and Radiowave Propagation, Russia, and installed in Moscow (55.5N,37.5E). Some results in regard to the reliability of the foF2, foF1, and ftEs autoscaled characteristics are presented and discussed. The flexibility of Autoscala is illustrated based on its modular structure.581 529 - PublicationOpen AccessCompatible analysis of vertical and oblique ionospheric sounding data(1996-08)
; ; ; ;Krasheninnikov, I. V.; Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation, Russian Academy of Sciences, Troitsk, Moscow Region, Russia ;Jodogne, J. C.; Institute Royal Meteorologique, Bruxelles, Belgium ;Alberca, L. F.; Observatory de l'Ebre, Roquetes, Tarragona, Spain; ; Examples are presented of the ray-tracing synthesis of multifrequency Oblique Sounding (OS) data on the Dourbes (Belgium) í Roquetes (Spain) path using electron density height profiles derived from Vertical Sounding (VS) measurements at both terminals. Comparison with the measured OS ionograms provides a means of assessing the accuracy of the VS true-height procedure POLAN. Particular attention was paid to a consideration of the E-F1 valley, that as concluded is often less deep than currently supposed, when derived using both ordinary and extraordinary components of the VS ionograms. Also, it was found that the peak of the F1 -layer should be expressed more distinctly (sometimes with a small valley between the F1 and F2 layers) though the corresponding VS ionograms may have no discontinuity in the region.166 309 - PublicationOpen AccessAutoscala: an aid for different ionosondes(2010-06)
; ; ; ; ;Pezzopane, M.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia ;Scotto, C.; Istituto Nazionale di Geofisica e Vulcanologia, Sezione Roma2, Roma, Italia ;Tomasik, L. ;Krasheninnikov, I.; ; ;Autoscala is a software to automatically scale ionospheric characteristics from an ionogram. Initially it was only applied to the ionograms recorded by the AIS-INGV ionosondes installed at Rome (41.8N, 12.5E), Gibilmanna (37.9N, 14.0E), Italy, and Tucumán (26.9S, 294.6E), Argentina, that are not able to record the polarization of the received echo. Recently Autoscala was also applied to the ionograms recorded by the AIS-Parus ionosonde installed at Moscow (55.5N, 37.3E), Russia, that is not able to tag the received echo in terms of polarization, and by the VISRC2 ionosonde installed at Warsaw (52.2N, 21.1E), Poland, that is instead able to perform the polarization tagging of the ordinary and extraordinary echoes. This work shows different examples of processing performed on ionograms recorded by all these three different types of ionosondes.372 633
