Seasonal characterization of particle extinction coefficient and its relation with PM2.5 mass concentration in Chengdu

Abstract

Abstract:

Daily PM_2.5 samples were collected in Chengdu for a period of one month in each of the seasons of 2011. Particle scattering coefficient and particle absorption coefficient were synchronously measured. The seasonal and daily variations in b_sp and b_ap and the relation between b_ext (b_sp+b_ap) and the PM_2.5 mass concentration was discussed based on above-measured data to investigate the causes of hazy weather. The results show that the annual b_sp and b_ap values were (456±237) Mm^-1 and (96±73) Mm^-1, respectively, and that daily variation in b_sp was influenced by metoroligical factors and transpotation of polltants from Chengdu suburban while daily variation in b_ap was influenced by metoroligical factors and local motor emission in the urban aera. Good correlation between PM_2.5 and b_ext was found (R²>0.92), which suggests that the higher PM_2.5 concentration is the key impact factor for hazy weather.

Key words: haze, particle scattering coefficient, particle absorption coefficient, particle extinction coefficient, PM_2.5
