Abstract:
The new Cross Calibrated, Multi Platform Ocean Surface Wind Velocity (hereafter,CCMP wind) products have been introduced, and the biases of CCMP wind fields are validated and evaluated against the wind measurements from satellite altimetry and in situ buoys. Furthermore, a comparison between CCMP wind fields and ERA Interim wind fields and QuickScat/NCEP wind fields is performed. The following conclusions can be drawn. The CCMP may have a negative mean speed difference in relation to the observations, and the best performance accurately occurs in open sea areas as well as a noticeable positive difference and trend in nearshore areas. In the East China Sea region, the CCMP has smaller absolute mean square errors and relative errors from the observed data compared with the ERA Interim wind fields and QuickScat/NCEP wind fields. The results have shown that the underestimation is mostly found for low wind speeds but overestimation for high wind speeds in these three kinds of wind fields, and a significant seasonal variation is also discussed.
