西北区域气象计量检定实验室量值比对分析

Comparison of Measurements from Northwest Regional Meteorological Metrology Laboratories

为验证西北区域各省(区)气象计量检定机构的检定能力,2014年宁夏气象计量检定所作为主导实验室组织开展温度、湿度、气压3个要素量值比对工作。比对采用圆环形路线,比对样品选用自动气象站传感器。参比实验室按照规定的比对方案对比对样品进行比对实验及不确定度评定,主导实验室对比对数据进行汇总分析,采用归一化偏差方法分析评价比对结果。比对结果:温度与气压实验室比对结果满意,湿度实验室比对结果较满意。参比样品的比对数据真实,结果可信,较为客观地反映了西北区域各参比实验室的检定/校准水平及气象计量标准装置的现状,有效识别了参加量值比对实验室存在的问题,对促进实验室检定能力的提高具有重要意义。

Measurement comparison is organized by the Ningxia Meteorological Metrology Calibration Laboratory to verify the calibration capability of the Northwest China meteorological metrological institutes.Temperature,humidity,and pressure are involved,and automatic weather station sensors are used in the experiments.The leading laboratory is in charge of data collection and analysis.The comparison result analysis is carried out by means of normalized standard deviation.The comparison results of temperature and pressure are very satisfactory,and that of humidity is satisfactory.The comparison test data is realistic and credible.The results can reflect the level of verification or calibration,and the current situation of meteorological measurement standard devices of reference laboratories objectively.It can also identify the problems existed in the reference laboratories effectively,which is very important in improving the capability of calibration laboratories.
