摘要：

采用分步反演、联合反演和线性回归的方法，分别实现海表盐度的反演。反演结果表明，分步反演可以及时发现和修正误差较大的参数，联合反演的精度最好，线性回归算法反演拥有最快的速度。在实际应用中，可以按需选择。

By using stepwise retrieval, coordinated retrieval or linear regression method, the sea surface salinity is inverted, respectively. The results show that the stepwise retrieval method can find and update parameter in time. The coordinated retrieval method is the best in accuracy while the linear regression method is the fastest. We can make choice according to our requirements in practice.
