Bibliography: | In this study ,the two-parameter algorithm is used to get the wind speed from HY-2 satellite radar altimeter. The correctness of this algorithm is verified using the Jason-1 and HY-2 scatterometer data qualitatively. Three different methods,such as cross-over method, NDBC buoys data validation and NCEP data test method are used respectively to evaluate this algorithm. It is turned out that the two-parameter retieval algorithm of the wind speed from ra-dar altimeter is considered to be accurate to 2.0 m/s. It meet the accuracy requirements of marine scientific research and applications. And HY-2 radar altimeter can provide users the observed surface wind products. wind speed retrieval; two-parameter algorithm; radar altimeter; HY-2 11-4421/G3 Jia Yongjun, Zhang Youguang, Lin Mingsen (National Satellite Ocean Application Service, Beijing 100081, China ) |
