Measurements of sea surface temperature (SST) can be made by satellite microwave radiometry in all weather conditions except rain. Microwaves penetrate clouds with little attenuation, giving an uninterrupted view of the ocean surface. This is a distinct advantage over infrared measurements of SST, which are obstructed by clouds. Comparisons with ocean buoys show a root mean square difference of about 0.6 degrees C, which is partly due to the satellite-buoy spatial-temporal sampling mismatch and the difference between the ocean skin temperature and bulk temperature. Microwave SST retrievals provide insights in a number of areas, including tropical instability waves, marine boundary layer dynamics, and the prediction of hurricane intensity.
除降雨天气外，在所有天气条件下都可通过卫星微波辐射测量法来测量海面温度（SST）。微波在穿透云层时衰减很小，从而能够不间断地观测海洋表面。这相对于红外海面温度测量而言是一个显著优势，因为红外测量会受到云层的阻碍。与海洋浮标的对比显示，均方根差值约为0.6摄氏度，这部分归因于卫星与浮标在空间 - 时间采样上的不匹配，以及海洋表层温度与整体温度之间的差异。微波海面温度反演在多个领域都能提供有价值的信息，包括热带不稳定波、海洋边界层动力学以及飓风强度预测等。
