摘要
本文给出了海洋二号(HY-2)卫星雷达高度计风速反演的双参数算法模型,并利用Jason-1产品和HY-2卫星微波散射计产品定性验证了双参数算法模型的正确性,同时利用星星交叉比对方法、美国国家浮标数据中心(National Data Buoy Center,NDBC)浮标数据验证方法、美国国家环境预报中心(National Centers for Environmental Prediction,NCEP)再分析数据验证方法三种不同方法对该模型进行定量化验证,结果表明HY-2卫星雷达高度计风速反演的双参数算法模型的反演精度达到2.0 m/s的精度,满足海洋业务应用和科学研究的精度要求,可为用户提供满足观测要求的海面风产品。
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.
