Abstract

Abstract

In this study,we evaluated three satellite remote sensing SST from AVHRR(Advanced Very High Resolution Radiometer),TMI(TRMM Microwave Imager) and AMSR-E(Advanced Microwave Scanning Radiometer for the Earth Observing System) using the in situ measurements obtained from the Chinese Antarctic Expeditions for the period 1989-2005,withem phasis on the Southern Ocean.Compared to the ship observations,AVHRR SST has a mean bias of -0.12℃ for day time and -0.04℃ for nighttime,and the cold bias is more pronounced in the Southern Ocean.TMI SST shows large warm biases relative to the observations(0.48℃ for day time and 0.57℃ for nighttime).The biases of TMI SST (△T) are influenced by 37 GHz wind speed,and the influence still exists even as the wind speed is higher than 6 m/s.AM SR-E SST also shows warm biases(0.34℃ for day time and 0.27℃ for night time),which are larger in the Southern Ocean as compared to other regions.The biases of AMSR-E SST are influenced by water vapor,particularly increasing with the increasing water vapor in the Southern Ocean.The comparison between the microwave(AM SR-E/TMI) and near infrared(AVH RR) SST suggests that the microwave SST is warmer in the tropical and Southern Ocean,but colder in the mid-latitude.In addition,for AMSR-E,the magnitude of the SST difference has a decreasing tendency from daytime to nighttime,whereas for TMI,there is not obvious change in the magnitude of the SST difference.
