Validation of sea surface wind vecter retrieval from China´s HY-2A Scatterometer

In this study, a comparison of wind field measurements from HY-2A Scatterometer and U.S. National Data Buoy Center (NDBC)´s moored buoys is performed. These comparisons were made in Pacific Ocean and Atlantic Ocean over one month period of August 2012. The SCAT wind speed retrieval agreed well with the buoy measurements, with mean differences of -0.74 m/s and standard deviations of 1.52 m/s. The results indicate that SCAT-derived ocean surface wind speeds are as accurate as other scatterometer, such as Quikscat and ASCAT. However, the wind direction retrieval still has some problems need to be investigated in the future.
