摘要：
In this work we present a technique for the assimilation of ocean surface current measurements into a numerical ocean model using data from High Frequency Radar (HFR) systems. Optimal interpolation of the model-predicted velocity and HFR observations is computed in order to derive a supplementary forcing applied at the surface boundary. This work is the first stage in the development of an HFR data assimilation system for hydrodynamic modelling in Galway Bay; it demonstrates the viability of adopting data assimilation techniques to improve the performance of numerical models in regions characterized by significant wind-driven flows.
