Impact of PM1 concentration on visibility and the aerosol hygroscopic growth factor in Guangzhou

doi:10.7523/j.issn.2095-6134.2014.03.015

Abstract

Abstract:

On the basis of long-term dataset (including aerosol mass concentration,black carbon concentration, scattering coefficient, visibility and extinction coefficient), the study gives the following three conclusions. First, visibility is negatively correlated with aerosol mass concentration. When the PM₁ mass concentration is greater than 60 μg/m³ visibility does not change significantly as the PM₁ mass concentration decreases, and when the PM₁ concentration is less than 60 μg/m³ visibility increases rapidly as the PM₁ mass concentration decreases. Secondly, the relative humidity has a major influence on the visibility. Thirdly, in Guangzhou aerosol hygroscopic growth factor and relative humidity has the following relationship: f(RH)=0.6+0.133×(1－RH/100)^－1.633. The local f(RH) is comparable to the growth curve of the IMPROVE with in the relative humidity range between 50% and 80%.

Key words: visibility, PM₁, relative humidity, the aerosol hygroscopic growth factor
