利用星载传感器观测数据反演的大气海洋参数进行综合研究是物理海洋学等海洋学科获取信息的重要手段。特别是全球尺度精细化的海面盐度信息,只有通过卫星观测才能有效获得。星载微波辐射计能够获取低频波段的亮温数据,具有一定的海面盐度反演能力。使用AMSR-E的C/X双波段垂直极化亮温数据和AMSR-E的L2b产品反演亚马孙河口海区和中国黄海东海海区的海面盐度,并将反演结果与WOA09气候态盐度数据进行比较。实验表明:使用星载微波辐射计的C/X双波段垂直极化亮温能够有效获得河口区域海面盐度的变化趋势,反演精度约为1.5psu,具有一定的应用价值,为将来我国盐度卫星的数据处理提供一定的帮助。
The comprehensive study of the atmospheric parameters of the ocean retrieved from satellite-borne sensor observations is an important means of obtaining information from marine sciences such as physical oceanography. In particular, refined sea level salinity information on a global scale can only be effectively obtained through satellite observations. The spaceborne microwave radiometer can obtain the brightness temperature data in the low frequency band, and has certain sea surface salinity inversion capability. Using AMSR-E C / X dual-band vertical polarization brightness temperature data and L2MS product of AMSR-E, the salinity of the sea in the Amazon estuaries and the East China Sea of the Yellow Sea in China was inverted and compared with the WOA09 climate salinity data Compare. The experimental results show that the C / X dual-band vertical polarized bright temperature using satellite microwave radiometer can effectively obtain the change trend of sea surface salinity in estuarine region. The inversion accuracy is about 1.5 psu, which has certain application value. In the future, Degree satellite data processing to provide some help.
