摘要
介绍了大气能见度研究的基本理论、消光系数的概念和计算方法,对国内外主流的透射式和前散射式能见度仪从优缺点、低能见度下数据对比和应用场所3个方面进行了比较分析。
The basic theory of atmospheric visibility studies, concepts and calculation methods of extinction coefficients are introduced firstly in this paper; and then some comparisons are made for mainstream transmission type meters and forward scatter meters inside and outside China from three points of view: advantage and disadvantages, low visibility data comparison and applications .
