针对海洋二号（HY-2）卫星扫描辐射计，利用辐射传射方程模拟，建立了海面温度、海面风速、大气水汽含量、大气液态水含量和雨率的反演算法，并利用扫描辐射计在轨数据对上述参数进行反演。经过对反演的海面温度和风速全球产品的真实性检验表明，算法合理可行，能够反演大气海洋参数，反演精度满足设计指标需求。目前，其他参数的反演产品的检验还在进行，而且反演算法还要根据对辐射计测量值定标的深入而进一步优化。

This paper established retrieval algorithm of sea surface temperature,sea surface wind speed,atmospheric water vapor content,atmospheric liquid water content and rain rate for the HY-2 scanning microwave radiometer using simulation data of radiation transfer equa-tion. And then we used on-orbit data to retrieve these parameters. The validation of sea surface temperature,sea surface wind speed shows that the algorithm is feasible and reasonable,which can retrieve the atmospheric and ocean parameters,and the accuracy meets the requirement of the design indicators. Currently,the validation of other parameters is still going on. The retrie-val algorithm will be optimized by further calibration of brightness temperature.
