摘　　要：自动气象站(AWS)观测资料是中尺度、短时效天气预报不可缺少的重要资料源之一。但由于AWS观测资料的特殊性,其质量问题不同程度地阻碍了它的使用。因此,AWS观测资料的质量控制越显重要。北京市气象局设计的自动气象站观测数据质量控制的方案主要是物理极值检查、历史极值检查、内部一致性检查、时间一致性检查、空间一致性检查等方法并把它应用于北京地区2007年奥运气象服务演练,取得了令人鼓舞的效果。结果表明:该质量控制方案的建立,能够实时反映北京市气象局自动站观测数据的可靠性,同时也反映出数据的缺测和及时性也存在一些问题。此系统的运行对2008年奥运气象服务,特别是对INFO2008和城市运行实时数据服务的可靠性将会发挥重要作用。Quality Control for data from automatic weather stations is very important with the development of society and technology. Beijing Meteorological Bureau has created real-time Quality Control system for automatic weather stations （AWS） which has applied on the 2007 Olympic Games Drilling. The scheme of Quality Control for data mainly includes methods, such as plausible value check, time c,）nsistency check, internal consistency check, history value check, spatial check, etc. The application of the data quality control system to 2007 Olympic Games Drilling in Beijing area shows that Beijing AWS data is reliable, but there are some problems on missing and timely data. This system will become a good example of real - time processing for AWS Quality Control in Beijing 2008 Olympic Games weather services.
