摘要

利用敦煌、北京等5个观测站的大气光学厚度[AOT(λ)]资料,分析了2001年春季中国北方大气气溶胶光学厚度的时空分布特征。结果表明,在观测期内各站每月都有大气气溶胶光学厚度高值[AOT(λ=0.50μm)≥1.04]出现,与我国北方历年在春季发生的沙尘天气的一般时空分布特征基本一致。本文还探讨了大气气溶胶光学厚度与水平能见度以及沙尘天气之间的关系。

Abstract

Using the Atmospheric Aerosol Optical Thickness(AOT) data at 5 stations,the characteristics of temporal and spacial distribution of AOT in the northern China in spring,2001 were analyzed.The results indicate that the higher values(≥1.04) of AOT often appear in each month at 5 stations during the observation period,and it seems to be same as the general temporal and spacial distribution features of the dusty weather occurred in the northern China in spring.The relationships between atmospheric aerosol optical thickness and horizontal visibility as well as the dusty weather were discussed.
