摘要：

利用Argo剖面浮标观测得到的近表层温度数据(NST),与两种卫星微波传感器(TMI和AMSRE)反演的海表温度(SST)进行较为系统的对比分析。结果表明,在南半球海域SST与NST虽存在显著的线性关系,但两者之间的差异(△T)还是十分明显的。无论是TMI还是AMSR-E反演的SST,与ArgoNST相比,△T均存在昼夜和季节变化:△T夜间较白天大,冬季达到最大,而春季则是最小。此外,△T还表现出沿纬线呈带状分布的特征。进一步研究表明,造成南半球海域SST与NST的差异主要由风速所致,且与海面流速和大气水汽含量也有一定的关系。为此,建议改进卫星遥感SST反演方法,缩小其与实测NST之间的差异,从而为南半球乃至全球海域多源SST融合提供更加可靠的统计学依据。

The microwave remote sensing sea surface temperature (SST) derived from TMI and AMSR-E and Argo near-surface temperature (NST) data in the Southern Hemisphere waters are compared. The result showed that the satellite SST and NST had remarkable linear relationship, but their difference (△T) was obvious. Whether derived from TMI or AMSR-E, △T showed diurnal and seasonal variation characteristics: the △T at night was greater than that at daytime, and the △T is maxmum in winter and is minimum in spring. Besides, the △T showed the characteristics of zonal distribution versus latitude. Further studies showed that, the difference between remote sensing SST and NST was resulted from the wind speed, and was also affected by the ocean surface velocity and water vapor. Therefore, it was necessary to improve the inversion method of satellite remote sensing SST to reduce the difference with the measured NST, and to provide a more reliable statistical basis for the merging of multiple SST in the Southern Hemisphere and even in the global ocean.
