中文摘要:

从测量微波成像器(TMI ) 和为观察系统(AMSR-E ) 的地球扫描辐射计的先进微波与非抽的近表面的温度(NST ) 相比的使命(TRMM ) 的热带降雨的导出卫星的海表面温度(SST ) 在全球海洋上从南船座介绍获得了漂流。可能引起温度差别的因素被检验,包括风速度,圆柱的水蒸汽,液体云水,和地理地点。结果证明 TMI 和 AMSR-E SST 高度与南船座 NST 被相关;以低风速度,然而,他们比南船座 NST 平均温暖。TMI 以低风速度比 AMSR-E 稍微好表现,而 TMI SST 检索可能糟糕以高风速度被校准。当圆柱的水蒸汽是低的时,温度差别显示 TMI/AMSR-E 的温暖的偏爱,它能显示既不 TMI 也不 AMSR-E SST 很好在高纬度被校准。在自台湾东面的菲律宾海流向日本的暖流延期区域的 SST 比在自台湾东面的菲律宾海流向日本的暖流区域有更高的可变性。检索卫星的 SST 和南船座 NST 之间的温度差别的可变性在春天期间在自台湾东面的菲律宾海流向日本的暖流延期是更低的。以低风速度,既不 TMI 也不 AMSR-E SST 很好被校准,尽管 TMI 比 AMSR-E 更好表现。

英文摘要:

Satellite-derived sea surface temperatures(SSTs) from the tropical rainfall measuring mission(TRMM)microwave imager(TMI) and the advanced microwave scanning radiometer for the earth observing system(AMSR-E) were compared with non-pumped near-surface temperatures(NSTs) obtained from Argo profiling floats over the global oceans. Factors that might cause temperature differences were examined, including wind speed, columnar water vapor, liquid cloud water, and geographic location. The results show that both TMI and AMSR-E SSTs are highly correlated with the Argo NSTs; however, at low wind speeds, they are on average warmer than the Argo NSTs. The TMI performs slightly better than the AMSR-E at low wind speeds, whereas the TMI SST retrievals might be poorly calibrated at high wind speeds. The temperature differences indicate a warm bias of the TMI/AMSR-E when columnar water vapor is low, which can indicate that neither TMI nor AMSR-E SSTs are well calibrated at high latitudes. The SST in the Kuroshio Extension region has higher variability than in the Kuroshio region. The variability of the temperature difference between the satellite-retrieved SSTs and the Argo NSTs is lower in the Kuroshio Extension during spring. At low wind speeds, neither TMI nor AMSR-E SSTs are well calibrated, although the TMI performs better than the AMSR-E.
