%X 风云四号A星是我国新一代静止轨道气象卫星的试验卫星，评估其海表温度产品的精度对海洋相关领域的研究和应用具有重要意义。以葵花8号海表温度产品为基准对2019年8月的风云四号A星海表温度产品进行了精度评价。研究结果表明：风云四号A星海表温度产品与葵花8号海表温度产品的时空分布比较一致，两者之间的平均偏差为0.23 K，平均绝对偏差和均方根误差分别为0.68 K和0.85 K。风云四号A星海表温度产品具有较高的精度，可以服务于气候监测和天气预报等研究领域。<br />
Fengyun-4A (FY-4A) is the first satellite of China’s new generation geostationary meteorological sat-ellites, assessing the accuracy of the FY-4A sea surface temperature (SST) product is of great significance to the research and application in related fields of the ocean. In this paper, we evaluate the accuracy of the FY-4A SST product in August 2019 using the Himawari-8 SST product as a bench-mark. The results show that the retrieved FY-4A SST product has a comparable accuracy with the Himawari-8 SST product, with a bias, mean absolute error and root mean squared error of 0.23 K, 0.68 K and 0.85 K, respectively. FY-4A SST product with the high accuracy can be used in the research fields of climate monitoring and weather forecasting.<br />
