Abstract
A TerraSAR-X Stripmap image over the North Sea shows significant spatial variations of sea surface wind field over the offshore wind farm Alpha Ventus. In the present study, we demonstrate the tempting potential of using high resolution SAR to investigate spatial variations of sea surface wind field over the offshore wind farms. A newly developed X-band Geophysical Model Function (GMF) XMOD2 is applied on the TS-X data to retrieve sea surface wind speed. By comparing the TS-X retrieved sea surface wind field to results of the DWD wind field, in situ observations on the FiNO platform, as well as the satellite measurement derived from the polarimetric microwave radiometer WindSat, it is found that the SAR estimated wind field not only agrees well with other measurements, but also presents the fine-scale features of sea surface wind field over the offshore wind farm.
