摘　　要：为了做好台站级区域自动站数据的质量控制工作,文章从极值、最大允许变化值、空间一致性、要素相关性等方面分析了有效的方法和本地化阈值,通过实例分析,Madsen-Allerup空间一致性检查、标准差对比法和线性回归估算法等检查方法均有较好的表现,业务人员可根据站点的具体情况进行分级检查。在降水的质控中,除常见方法外还给出了结合雷达反射率和降水阈值的判定方法,以减少误判。希望研究结果能为区域自动站数据质量控制工作提供参考。In order to do a good job in the quality control of automatic station data at the station level,this article analyzes effective methods and localization thresholds from the aspects of extreme values,maximum allowable change values,spatial consistency,and element correlation.Through example analysis,Madsen-Allerup spatial consistency check,standard deviation comparison method,and linear regression estimation method have all performed well.Business personnel can conduct grading checks according to the specific situation of the station.In the quality control of precipitation,in addition to common methods,a judgment method combining radar reflectivity and precipitation threshold is also provided to reduce misjudgments.It is hoped that the research results can provide reference for the quality control of regional automatic station data.
