HY-2卫星雷达高度计风速反演验证
Verification of HY-2 satellite radar altimeter wind retrieval
摘要
Abstract
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 ma-rine scientific research and applications. And HY-2 radar altimeter can provide users the ob-served surface wind products.关键词
