Gonçalves, M. and Guedes Soares, C. (2025), Wave hindcast correction model based on satellite data in the Azores Islands, Oceans, Vol. 6, 17.
A mathematical wave forecast for the area surrounding the Azores Islands is presented here. The SWAN model is used to produce wave conditions in the Azores for a 6-year period. The model obtains boundary conditions from a North Atlantic Wavewatch 3 model. Both models are forced with ERA5 wind fields. This study proposes and analyses two correction methods, a least-square linear regression and a bias correction, to improve the hindcast results by assimilating altimeter satellite data. The results show reductions in the error values and reductions in the data dispersion for one of the methods used. There is an increase in the correlation between measurements and observations. Better results are obtained with the bias correction method.
