Offshore new European wind atlas

Abstract

The New European Wind Atlas (NEWA) is a joint research effort from eight European countries, co-funded under the ERANET Plus Program. The final aim is the creation and publication of an electronic European wind atlas. An offshore wind atlas extending 100 km from the European coasts is foreseen within the project, based on mesoscale modelling and various observational datasets. Satellite wind retrievals from scatterometers and Synthetic Aperture Radar (SAR) instruments are used to validate offshore modelled wind fields and identify the optimal model set-up parameters. The aim of this study is to present the initial outputs from the offshore wind atlas produced by the Weather & Research Forecasting (WRF) model, still in pre-operational phase, the METOP-A/B Advanced Scatterometer (ASCAT) and SAR derived winds. Different experiments were set-up to evaluate the model sensitivity for the various domains covered by the NEWA offshore atlas. ASCAT winds are utilised to assess the performance of the WRF offshore atlases. In addition, ASCAT winds were used to create an offshore atlas covering the years 2007 to 2016, where various spatial wind characteristics, such as channelling and lee effects from complex coastal topographical features, were visualised.
