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 principle of measuring the sea surface temperature by the infrared radiometer and the microwave radiometer is introduced, and the differences between them in inverting the sea surface temperature are analyzed. In remote sensing of sea surface temperatures worldwide, remote sensing accuracy of infrared radiometers and microwave radiometers is affected by many factors. Sensor itself, the accuracy of the algorithm, the sensor resolution, the global coverage of the carrying satellites and other factors make the radiometer detection data differences; atmospheric conditions, sea surface winds, the sea temperature measurement of different depths of water temperature and other external factors At the same time affect the infrared radiometer and microwave radiometer remote sensing accuracy. Knowing the pros and cons of the radiometers in the infrared and microwave bands will help you to develop their own specialties and effectively improve the accuracy of the satellite’s temperature monitoring of the sea surface.
