- PublicationOpen AccessIonosphere-plasmasphere response to geomagnetic storms studied with the RMI-Dourbes comprehensive database(2002)
; ; ;Jodogne, J. C.; Royal Meteorological Institute of Belgium,Brussels,Belgium ;Stankov, S. M.; Royal Meteorological Institute of Belgium,Brussels,Belgium; Presented is a review of the ionospheric storm research carried out at the Royal Meteorological Institute (RMI)of Belgium.The studies are based on the opportunities offered by the long-term measurements and the accumulated comprehensive database managed by the RMI Geophysics Centre at Dourbes (4.6 °E,50.1 °N).Reported are case studies of major storms,and also results in developing forecasting and density reconstruction methods.239 391 - 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
