雾探测器现场对比试验方法研究

简单介绍了WT-1型雾探测器的结构和现场试验情况，对试验期间(2001年12月1日至2002年5月31日)所获取的数据进行了统计分析，计算了试验期间雾探测器数据的缺测率、与人工观测数据及芬兰同类产品的测量结果之间的相关系数，三者之间的相符率，以及数据随时间的变化趋势。以数据处理结果为依据，客观地阐述了雾探测器的优缺点，以及与目前世界上普遍认可的芬兰能见度仪之间的差距，同时也提出了雾探测器改进的一些建议。

Field Comparison Test of WT-1 Fog Detectors

The field tests of WT-1 Fog Detectors are described and the acquired data during the tests are analyzed statistically. The absent rate of observation data from the WT-1 and FD12P, the correlation coefficients of WT-1 with visual observation and FD12P, the conformability of the three measurements and the variation trend of the difference with time are calculated. Based on the analysis results, the advantages and disadvantages of the detector are discussed. In comparison with Vaisala's visibility sensor FD12P, the difference between WT-1 Detector and FD12P is described, and improvement suggestions are proposed.
