Wang, X. (author), Verlaan, M. (author), Apecechea, Maialen Irazoqui (author), Lin, H.X. (author)Accurate parameter estimation for the Global Tide and Surge Model (GTSM) benefits from observations with long time-series. However, increasing the number of measurements leads to a large computation demand and increased memory requirements, especially for the ensemble-based methods that assimilate the measurements at one batch. In this study,...journal article 2022

Wang, X. (author), Verlaan, M. (author), Apecechea, Maialen Irazoqui (author), Lin, H.X. (author)In this study, a computation-efficient parameter estimation scheme for high-resolution global tide models is developed. The method is applied to Global Tide and Surge Model with an unstructured grid with a resolution of about 2.5 km in the coastal area and about 4.9 million cells. The estimation algorithm uses an iterative least squares...journal article 2021
