This paper compares the L3 product of QuikSCAT 10 m Scatterometer Winds with the fishing vessels' wind data. The statistical biases between the two sets of data show that:① in general, the fishing vessels' wind speed of offshore Chile is higher than QuikSCAT,and the wind direction of fishing vessels is on the left side of the QuikSCAT ;②the wind speed bias between the fishing vessels and QuikSCAT wind data is concentrated on the range of -- 1 - 1 m/s, and the wind direction bias is mainly in the range of -60°-10°,with minor range of 10°-60° and --10°-10°;③ the wind speed deviation characteristic value in the day time is better than that at night,and there is distinct difference of wind direction mean bias be- tween day and night ,but the absolute bias and root mean square bias of wind direction are similar;④ and the biases between the fishing vessels' winds and QuikSCAT wind data in 2008 are larger than the average of other years, especially for the wind speed bias of high wind speed section.
