海南省实时能见度质量控制方法及应用

Research on Quality Control Method of Real-time Visibility of Hainan

现行的质量控制系统对能见度的质量控制方法较为简单,存在许多疑误信息被漏检。为解决此问题,利用2017年9月至2018年8月海南岛与南海海岛小时能见度数据,采用线性回归方法建立海南省不同季节不同地域能见度与其相关要素数据的线性拟合方程,并将其运用于内部一致性检查中。经检验,基于该拟合方程的质量控制方法对能见度数据质量控制效果较好。

The quality control method of visibility in the current quality control system is relatively simple,and there are a lot of doubtful and erroneous information to be missed.In order to solve this problem,the hourly visibility data of Hainan Island and South China Sea Island from September 2017 to August 2018 was analyzed.The paper used the method of linear regression to establish the linear fitting equation of the visibility and its related factor data in different seasons and different regions of Hainan Province,then applied it to the internal consistency check.The results showed that the quality control method based on this linear fitting equation had a good effect on the visibility data.
