摘　　要：为确保南海海岛气象站资料的可靠性、可用性,本文通过对南海区域站实时气象资料原有质量控制方法得出的疑误信息进行分析,利用增加双站对比检查和对空间一致性检查方法进行改进,对南海区域站实时气象资料进行质量控制,以降低南海区域站正确数据被检测为疑误数据的概率。应用新质量控制方法对2015年9月至2016年7月南海区域站数据进行质量控制,剔除的误检信息占原疑误信息的71.7%,疑误检出后的准确率有较大提高。The South China Sea is an important part of Chinas territory,and it has a great strategic significance for China.In order to ensure the reliability and availability of the data from the island weather stations,this paper analyzes the error messages that are generated by the original quality control system,and in order to reduce the number of false checks for the regional automatic stations on the South China Sea,a method is developed,which can check the data difference between two stations on the same island,and the spatial consistency check method is improved.By using the new method to check the data of the regional automatic stations on the South China Sea from September 2015 to July 2016,the removed false check messages accounts for 71.7% of the original false check messages.The accuracy of error detection is greatly improved.
