对覆盖至少20年的6个全球、格网、无间隙的每日海表面温度(SST)分析进行了相互比较：ESA SST CCI分析长期产品v1.0、MyOcean Ostia再分析v1.0、CMC0.2度、AVHRR_Only每日1/4度OISST v2.0、HadISST2.1.0.0和MGDSST。所有六个集合的中位数的第七个SST产品也使用GMPE(高分辨率SST多产品集合组织)系统进行了制作。对独立的近地表ARGO数据进行了验证，使用了从热带到GMPE中值的系泊浮标数据的长时间序列，以检查分析的时间和空间一致性。还对这些分析的特征分辨率进行了比较。总结了SST数据集的相对优势和劣势，旨在帮助用户明智地选择最适合其拟议应用的分析。
Six global, gridded, gap-free, daily sea surface temperature (SST) analyses covering a period of at least 20 years have been intercompared: ESA SST CCI analysis long-term product v1.0, MyOcean OSTIA reanalysis v1.0, CMC 0.2 degree, AVHRR_ONLY Daily 1/4 degree OISST v2.0, HadISST2.1.0.0 and MGDSST. A seventh SST product of the ensemble median of all six has also been produced using the GMPE (Group for High Resolution SST Multi-Product Ensemble) system. Validation against independent near-surface Argo data, a long timeseries of moored buoy data from the tropics and anomalies to the GMPE median have been used to examine the temporal and spatial homogeneity of the analyses. A comparison of the feature resolution of the analyses has also been undertaken. A summary of relative strengths and weaknesses of the SST datasets is presented, intended to help users to make an informed choice of which analysis is most suitable for their proposed application.
