The model is evaluated by making internal tide correction to independent altimetry data in 2023. ZHAO30yr performs much better than ZHAO20yr, a model developed using 20 years of data by an obsolete mapping technique. ZHAO30yr is a fruit of 30 years of satellite altimetry operation by the international satellite altimetry community. The model may find its applications in a wide variety of scientific research and practice. ZHAO30yr is a new-generation model, because it decomposes the internal tide field and reveals numerous long-range internal tidal beams, which contain key information on their generation, propagation, and dissipation. In contrast, all previous empirical internal tide models only give the multiwave summed amplitudes and phases.
