ECHOWAVE is the acronym used for European COasts High Resolution Ocean WAVEs Hindcast. The dataset was developed using WAVEWATCH III and has a resolution of approximately 2Km with a duration from 1990-2021 at hourly (1-hr) intervals. The coverage are the European Atlantic coastlines.The model employed a 2-way nesting multi-grid scheme to progressively increase spatial resolution closer to the coast (to about 2.3 km). The hindcast generation was designed specially to provide reliable sea states’ characterization for wave energy applications. Primarily, to reduce uncertainties in the wave resource estimation within European coastal waters. In this sense, there are 3 main characteristics from this dataset to highlight.(1) All physical parameterizations adjustments are applied to improve the performance within the North-East Atlantic. This approach allowed to reduce the bias for a wide range of wave heights in the area of interest (compared to existing datasets).(2) Adjustments’ verification and extensive validation is done using the latest ESA Sea State CCI V3 altimeter dataset, which is adequate for coastal applications.(3) High resolution within coastal areas, for depths ≤200 m, allows for a detailed characterization of the wave resource at nearshore and coastal areas.
