Short summary

We studied chemical compositions and chromophores of brown carbon aerosol from combustion emission before and after photooxidation using an oxidative flow reactor. The chromophore and chemical composition of brown carbon were determined by excitation-emission spectroscopy and mass spectrometry. This work helps to get a better understanding of evolution process of the chromophores from primary combustion emissions during the real atmospheric transportation.
