Fig. 8

The schematic figure of the traveling ionospheric disturbance and the ray paths of the radio waves. The top panel (a) shows the TID and the raypath of the radio waves. The bottom panel (b) shows a bird’s-eye view of the iso-contour of the ionospheric electron density and the ray paths of the radio waves between Chofu and Sarobetsu
