摘 要: 将芬兰VAISALA公司的MITRAS大气透射仪自动观测的能见度与人工观测的能见度记录进行对比,分析两种观测数据的差异,通过统计分析,找出他们之间的关系。研究结果表明:1) 能见度较好时,自动观测系统观测的能见度与人工观测的能见度偏差较大,而且幅度没有明显的规律性;2) 低能见度时,自动观测与人工观测记录的一致性较好,自动观测的能见度比人工观测的能见度值偏高;3) 低能见度时,自动观测系统得出的数据更客观、更具有代表性。
关 键 词: 大气科学;能见度;自动观测;人工观测;数据;分析

Abstract: This paper compares the visibility observed automatically by MITRAS atmospheric transmissometer made by VAISALA Company in Finland with the visibility record of artificial observation, analyzes the difference between these two kinds of observation data, and finds out the relationship between them through statistical analysis. The results show that: 1) when visibility is high, the bias of visibility between automatic observation and artificial observation is large, but the range has no apparent regularity; 2) when visibility is low, the visibility of automatic observation is in accord with the visibility of artificial observation, but the visibility of automatic observation is a little higher than the visibility of artificial observation; 3) when visibility is low, the data of automatic observation is more objective and more representative.
Key words: atmospheric sciences; visibility; automatic observation; artificial observation; data; analyze
