摘要
运用持续性检查和空间一致性动态阈值的自动质量控制方法,对2016年6月至2022年12月广西91个气象观测站“回南天”逐时观测资料进行质量控制,分析瓷砖地面温度和墙面温度错误数据量最多和最少的5个站,对观测数据错误较多的气象站进行实例分析。结果显示,界限值、气候极值、内部一致性、时间一致性、持续性、空间一致性和综合性检查的自动质量控制方法,能明显提高错误观测数据的检出率,为有效提升“回南天”观测数据质量提供可靠的技术方法。
Using the automatic quality control method based on persistence checks and dynamic thresholds for spatial consistency,this paper carried out quality control on the hourly observations data of“Continuous Wet Weather”at 91 meteorological stations in Guangxi from June 2016 to December 2022,and analyzed the five stations with the highest and lowest volumes of erroneous data in tile surface temperature and wall temperature measurements.Case studies were conducted on stations exhibiting higher error rates.The results demonstrate that the automatic quality control approach—integrating threshold verification,climatic extremes validation,internal consistency checks,temporal consistency checks,persistence checks,spatial consistency checks,and comprehensive evaluation—significantly improves the detection rate of erroneous observational data.This method provides reliable technical support for effectively enhancing the quality of“Continuous Wet Weather”observation data.
