Model test: reconstruction of the tsunami wave through the assmilation of the sea surface height (SSH) measurements.

Figure 1. Tsunami wave generated by initial "Gaussian" rising of the SSH in the center of the square domain.

Figure 2. Reconstructed evolution of the tsunami wave. SSH data from 14 coastal locations (circules) were assimilated into the model.

Figure 2. Reconstructed evolution of the tsunami wave. SSH data from 14 coastal locations and 2 additional locations in the center of the ocean domain were assimilated into the model.
Comparison between Figures 2 and 3 shows that SSH measurements in the central part of the ocean can significantly increase the quality of the reconstruction.
