Assessment of the use of scatterometer wind data to force wave models in the North Atlantic Ocean

The present work uses for the first time scatterometer wind fields to force a wave model and compares accuracy of resulting conditions with ones obtained when using two different sources hindcast forcing same spectral in Atlantic Ocean. For this purpose, 5-year (2010–2014) is performed SWAN Madeira Azores archipelagos. as input bathymetry from GEBCO, boundary WAVEWATCH III provided by Ifremer winds ERA-Interim ERA5 databases, remotely sensed scatterometers. A quantitative analysis results performed, numerical are validated against altimeter data buoy measurements. Globally, ERA-Interim, similar generated fields, expressed error statistics, which very close each other, but case extreme events, reveals more intense consequently lead sea states higher significant height. This visible area than Madeira. demonstrate that, general, height well reproduced SWAN.
