Outline
The sea surface temperature (SST) products, obtained from the Chinese Ocean Color and Temperature Scanner (COCTS) on the two haiyang satellites (HY1C and HY1D), play an important role in oceanic and atmospheric researches. It is important to know whether they are consistent with products from other satellites such as the Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra and Aqua satellites. The data quality of SST global images from COCTS on HY1C/1D is evaluated by the average bias, absolute difference, root mean square error, and correlation coefficient based on in-situ SST measurements and the MODIS products. The results show that the spatial patterns of the daily and monthly global SST of HY1C/1D are similar to those of Terra/Aqua. The average bias, absolute difference, root mean square error and correlation coefficient of the global daily SST/HY1C products at daytime, based on the SST values of Terra on June 2020, are 0.04℃, 0.60℃, 0.78℃ and 0.98, respectively, and that of the nighttime products are −0.16℃, 0.78℃, 0.95℃ and 0.86, respectively. Similarly, the values of the daytime SST products of HY1D comparing with the SST of Aqua on June 2020 are 0.02℃, 0.59℃, 0.79℃ and 0.98, and that of the nighttime products are −0.09℃, 0.61℃, 0.82℃ and 0.96, respectively. The evaluation on other seasons indicates that the SST products from COCTS are very stable. However, the data quality control scheme and inhomogeneity correction still need to be developed to improve the performance of SST products of HY1C/1D. As a whole, the SST products of HY1C/1D can be used in some applications, similar to the Terra/Aqua products.
