| 摘 要： | Belfort M6400型是Belfort仪器公司在M6000型基础上在软件和硬件方面均作出优化和完善后生产的成本更低的、观测更高效的能见度观测仪。本文利用2021年6月11日至7月11日番禺国家气象观测站的Belfort M6000型能见度仪与Belfort M6400型能见度仪观测数据作比对试验，分析两款能见度仪的观测差异特征及气象要素的关系。结果表明，（1）两款能见度仪观测的分钟平均能见度的变化趋势较为一致，二者相关系数为0.92；（2）随能见度等级的增加，差值范围和离散程度均有所增大；（3）两款能见度仪观测值与相对湿度呈负相关关系，与气压呈正相关关系，与其他气象要素的关系不明显；（4）两款能见度仪在雨天时的日平均相关系数（0.93）比晴天（0.82）时要高。

| Abstract: | Belfort M6400 is a lower-cost and more efficient visibility observer produced by Belfort Instruments on the basis of M6000 in terms of software and hardware. This paper uses the Belfort M6000 visibility meter and the Belfort M6400 visibility meter observation data of the Panyu National Meteorological Observatory from June 11 to July 11, 2021 for comparison experiments, and analyzes the characteristics of the observation differences and meteorological elements of the two visibility meters. relation. The results show that (1) The change trend of the average minute visibility observed by the two visibility meters is relatively consistent, and the correlation coefficient between the two is 0.92; (2) With the increase of the visibility level, the range of difference and the degree of dispersion both increase; ( 3) The observation values of the two visibility meters are negatively correlated with relative humidity, positively correlated with air pressure, and have no obvious relationship with other meteorological elements; (4) The daily average correlation coefficient (0.93) of the two visibility meters in rainy days is more than It is higher on sunny days (0.82). |
