Short summary
We found significant seasonal variations in optical and chemical properties of organic aerosols in the urban region and changes in
photo-resistivity of light-absorbing organic aerosols (e.g., brown carbon) owing to the high UV radiation in the atmosphere. Our results suggest that photochemical degradation plays a significant role in light-absorbing organic aerosol abundances and might be an important removal mechanism of
light-absorbing aerosols in the atmosphere.
We found significant seasonal variations in optical and chemical properties of organic aerosols...
