摘　　要：[目的]研究区域自动气象站后端实时数据质量控制的方法。[方法]介绍了区域自动气象站后端实时数据质量控制的基本内容和步骤,对各要素进行系统的质量控制流程规范,深入分析广西区域自动气象站后端实时数据错误的存在形式,并结合要素的相关和线性变化规律,在传统质量控制方法基础上进行改进,对气温、气压要素采用预估值检查、要素相关检查等方法进行质量控制。[结果]该方法是在传统质量控制方法基础上进行优化和改进,缩短了实时数据质量控制的时效;小时降水量质量检查采用小时最低温度相关检查、雷达资料垂直一致性检查,有效提高小时降水量质量控制准确度和可信度。[结论]该方法已在广西区域自动气象站实时资料质量控制试用一年,并取得良好的效果。[Objective] The aim was to study the rear-end real-time data quality control method of regional automatic weather station.[Method] The basic content and steps of rear-end real-time data quality control of regional automatic weather station were introduced.Each element was treated with systematic quality control procedure.The existence of rear-end real time data of regional meteorological station in Guangxi was expounded.Combined with relevant elements and linear changes,improvement based on traditional quality control method was made.By dint of evaluation and relevant check of element,the quality of temperature and pressure was controlled.[Result] The method was optimized based on traditional quality control method,and it narrowed the effectiveness of real-time data quality control.The quality check of hourly precipitation applied relevant check of hourly minimum temperature,vertical consistency check of radar data,which can effectively improve the accuracy and credibility of hourly precipitation quality control.[Conclusion] The method has been on trial for one year in the quality control of real-time data in the regional automatic meteorological station in Guangxi and has gained good outcome.
