Abstract

Online processing of SAR to wind maps is ongoing, and the series of wind maps are used for investigation of offshore wind resources. In wind energy the siting of a wind farm is dependent upon reliable information about the wind climate within the area of interest. Offshore this information is hard to retrieve as it is costly to install and maintain offshore meteorological masts and very few reliable data sets exits. Typically a meteorological mast is erected for the purpose of calculating the wind resource. An alternative approach using satellite SAR images has been developed and tested. The results are fairly good and the method is growing into an applied routine. Results from an in-depth study in the Scandinavia Seas will be presented. In this offshore area around 15 offshore wind farms are operating and more are in construction. Thus the study is focussed on an area with major offshore wind power capacity.
