Short summary
By attributing the shortwave absorption from black carbon, primary organic aerosol and secondary organic aerosol in a suburban environment, we firstly observed that the photochemically produced nitrogen-containing secondary organic aerosol may contribute to the enhancement of brown carbon absorption, partly compensating for some bleaching effect on the absorption of primary organic aerosol, hereby exerting radiative impacts.
