Fig. 9From: Sensitivity of ionosonde detection of atmospheric disturbances induced by seismic Rayleigh waves at different latitudesSynthesized ionograms (O-mode only) for \(I=72^\circ\) (orange) and \(45^\circ\) (green) corresponding to ionospheric disturbances in Fig. 8. The virtual height at each frequency is plotted by a symbol “ | ” representing the sounder pulse width so that the plots look like actual ionogramsBack to article page
