Short summary
Sunlight affects the life and chemical composition of atmospheric aerosols and thus alters air quality. This study demonstrated that the photo-aging process not only changed the chemical compositions of chromophoric aerosols but also changed the roles of the chromophoric organic matter in the photo-aging process of aerosol. This study adds to our understanding of how sunlight affects chromophoric aerosol aging.
