Comparison between QuikSCAT and buoy wind data in the north Yellow Sea
北黄海QuikSCAT 卫星风速与浮标风速的对比分析

We compared the wind data obtained from QuikSCAT satellite with that measured in situ in the north Yellow Sea at an offshore buoy deployed by Institute of Oceanology, the Chinese Academy of Sciences. The bias between QuikSCAT wind speed data and the buoy-measured data satisfied the accuracy requirement. The mean bias for wind speed was about 0.26 m/s and the correlation between the two data was 0.74. However, the bias with mean of 117.52° for wind direction between the two wind data was too large. A correction method for QuikSCAT wind direction was proposed on the basis of the comparison. The mean bias for wind direction was about 20.44° after the correction.
