金沙大气本底站酸雨观测质量考核的质量控制

Qualityr Control of Acid Rain Observation Quality Assessment at Jinsha Atmospheric Background Station

酸雨水样测量结果的准确性对于研究酸雨时空分布、治理和防治十分重要。湖北金沙大气本底站现用质量控制的极值法和比较法,无法保证酸雨观测数据的准确度。结合金沙大气本底站多年的考核工作情况,从酸雨样品考核的目的和评分标准、测量误差的分类、酸雨测量误差的来源等方面进行分析,提出酸雨测量的质量控制方法,有利于台站提高酸雨观测质量的提高。

The accuracy of measurement results of acid rain water samples is very important for the study of acid rain spatial and temporal distribution,treatment and prevention.Extreme value method and comparison method of quality control currently used in Jinsha atmospheric background station cannot ensure the accuracy of acid rain observation data.Combining with the assessment work of Jinsha atmospheric base station for years,we analyzed the purpose and criteria of acid rain sample assessment,the classification of measurement errors and the sources of acid rain measurement errors,and introduced the quality control method of acid rain measurement,which is conducive to improving the quality of acid rain observation at weather stations.
