Abstract: This study takes the VIIRS sea surface temperature (SST) products from 2012 to 2016 as the object. The data from Argo buoys was taken as main verification and from MODIS Terra and MODIS Aqua as auxiliary verification while the time scale and space scale was used as controls. Results show that VIIRS SSThas a mean bias of -0.015 5℃ and standard deviation of 0.514 0°C during daytime and has a mean bias of -0.221 4℃ and standard deviation of 0.418 9℃ during nighttime. Mean bias of VIIRS SSTat daytime is closer to the Argo buoy observations than that at nighttime. VIIRS SSThas seasonal variation both at daytime and nighttime and its mean bias in summer is greater than that in winter. During daytime, VIIRS SSTis higher in the equatorial Pacific Ocean and near the equatorial Indian Ocean than Argo buoys. At nighttime, it is generally lower than that of buoys, and there is little difference in the spatial distribution of standard deviations during daytime and nighttime. Compared with monthly mean deviation of MODIS Terra and MODIS Aqua SSTproducts, VIIRS SSTin summer is lower than MODIS Terra SSTin the southern hemisphere while in winter it is also lower than MODIS Terra SSTin the midhigh latitudes of the northern hemisphere. VIIRS SSTis lower than MODIS Aqua SSTin some areas of summer and in most areas of winter.
