摘　　要：主要介绍了风云二号静止气象卫星海面温度产品的质量检验方法及检验流程,给出了FY2E业务海面温度产品和FY2F海面温度算法的质量检验结果,并从误差统计、反演算法、系统设计等方面分析了目前FY2海面温度产品与国外卫星海面温度产品差异大的原因。现场海面温度质量检验和分析场海面温度交叉检验各有优缺点。现场海面温度质量检验能够对FY2 SST产品给于客观的评价。国外分析场海面温度具有时效性好、全球覆盖且质量均一的优点,分析场海面温度交叉检验能满足FY2 SST质量检验的时效性,是对FY2 SST的相对检验。通过静止卫星海面温度产品质量检验信息可以为产品研发人员和相关用户提供参考。Quality validation methods and validating process of FY 2 geostationary meteorological satellite sea surface temperature （SST） products are introduced. The validation of operational SST product of FY2E and SST retrieval algorithms of FY2F are given out. At present, compared with foreign satellite SST, the accuracy of FY2 SST is poorer because of various reasons, such as the error statistics method, the retrieval algorithm and the system design, etc. In situ SST validation and cross product SST validation have their own advantages. In situ SST validation can give an objective evaluation of FY2 SST product. Analysis SST field has the advantages of global coverage, good timeliness and a more uniform quality. The cross product SST validation by analysis SST field for FY2 SST can meet the need of timeliness, which can also provide relative quality information. The geostationary satellite SST product validation information can provide a reference for product development and related users.
