Assessment of the use of scatterometer wind data to force wave models in the North Atlantic Ocean
International audience The present work uses for the first time scatterometer wind fields to force a wave model and compares the accuracy of the resulting wave conditions with the ones obtained when using two different sources of hindcast wind fields forcing the same wave spectral model in the Atlan...
