Figure 8: Same as Figure 5 but for HYDE29 and simulated tsunami is at 6UT
The time-distance plots of tsunami induced ionospheric perturbation presented in Fig. 9 show distinct aliases in dTEC at BAN231, COCO02, COCO04, DGAR07, and IISC11. The perturbations derived using differential method (dTEC) contain signal aliases associated with inter-IPP distance in 27% of the detected cases (Table 1) when compared to gROT which is free of any such aliasing.
