摘　　要：介绍了红外辐射计和微波辐射计测量海表面温度的原理,分析了它们各自在反演海表面温度时的差异。在全球范围的海表面温度的遥感监测中,红外辐射计和微波辐射计的遥感精度受到多种因素影响。传感器本身的噪音、算法反演精度、传感器分辨率、搭载卫星的全球覆盖率等自身因素使辐射计的探测资料产生差别;大气状况、海面风速、测量海洋不同深度海水的表征温度等外界因子也同时影响着红外辐射计和微波辐射计的遥感精度。了解红外波段和微波波段的辐射计在各方面的优劣,有助于发挥各自特长,有效提高卫星监测海表面温度的精度。The basic principles of the sea surface temperature （SST） remote sensing using infrared and microwave radiometers are introduced, and the differences between two sensors for retrieving the sea surface temperature are investigated. The ground resolution, atmospheric effects, sea surface wind, skin depths, and so on have important influence on the precision of the sea surface temperature retrieved by two sensors. The better understanding of the advantage and disadvantage of the sea surface temperature help us to enhance the accuracy of the SST remote sensing detected by infrared and microwave radiometers would data more effectively.
