A Review of Global Ocean Tide Models for Tidal Prediction to Support Hydrographic Separation Model
摘要
The ocean tide model is critical for determining accurate vertical datum transformations with high accuracy and resolution. The advent of satellite altimeters has increased the accuracy of tidal predictions for the open ocean by around 2 cm. However, there are significant variations in shallow water and coastal zones, which could correspond to the complex hydrodynamic systems and a lack of high-quality satellite altimetry data. Hence, an overview of the global tide model is performed to evaluate the performance of global ocean tide models in open ocean and coastal areas. This paper attempts to review the performance of several tide models based on the previous comprehensive tests. Such an attempt foresees the potential application of local hydrodynamic models for accurate tidal prediction and could provide an opportunity to produce a seamless hydrographic separation model in coastal and offshore areas, especially in Malaysian waters.
