对温度湿度气压国际比对结果的进一步分析
Reanalysis of Interlaboratory Comparison in the Field of Temperature, Humidity and Pressure
中文摘要：
欧洲气象计量研究计划（MetroMet），继WMO RA VI实验室比对（ILC）后，世界气象组织RAⅡ，Ⅴ和Ⅵ的区域仪器中心（RIC）参加了温度、湿度和气压量值的实验室比对。比对采用圆环形传递路线，主导实验室依次完成测试后，参比实验室相继测试，然后主导实验室再次测试，直至闭环。比对协议指出参考值取主导实验室的两次量值的加权平均值；本文指出参考值取全部实验室的单次量值的加权平均值，然后利用各实验室报告的比对结果，分别采用不同算法确定2个参考值，用归一化偏差En值作为比对判据评价各实验室的测量结果。比较两个不同参考值的结果评价情况，验证参比实验室在比对评价不满意的测量点与每个主导实验室的数据兼容性，说明采用全部实验室的单次量值计算参考值的算法更合理。

Abstract：
Following the Interlaboratory Comparison (ILC) completed in WMO RA Ⅵ under the MeteoMet project of Europe, a further Interlaboraroty Comparison focusing on atmospheric temperature, humidity and pressure was started in the Regional Instrument Centers (RIC) of WMO RA Ⅱ, Ⅴ and Ⅵ. The ILC was performed in a round-robin scheme, with a single loop. Every pilot laboratory performed two sets of measurements, at the beginning and at the end of the loop. And the participating laboratories performed their measurements in between. According to the ILC, the reference value for calculation was based on the weighted mean from the pilot laboratories. In this paper, it is proposed that the reference value for calculation be based on the weighted mean from all laboratories. Using the comparison results from each laboratory, two reference values were determined by different algorithms. And the measurement results of each laboratory were evaluated with reference to En numbers. Furthermore, The effects of two reference values on the evaluation results were compared to verify the data compatibility between the participating laboratory and the pilot laboratory in terms of the unsatisfying results from some measurement points of the former. The analysis shows that, compared to the calculation method that takes the weighted mean from the pilot laboratories as the reference value, it is more reasonable and equitable to take the weighted mean from all the laboratories as the reference value.
