Abstract Two field campaigns were conducted using a three-wavelength photo-acoustic soot spectrometer (PASS-3) and aerosol mass spectrometers (AMS), including urban site Jinhua during autumn 2011 and rural site Wangdu during summer 2014 in this study. Light absorption of brown carbon with improved Absorption Angstrom Exponent (AAE) method was evaluated by extrapolating the more realistic AAE by "pure" BC (AAE__BC). The AAE__BC were found to be 1.12, 0.77 between 405nm and 781nm, and 0.87, 0.63 between 532nm and 781nm in the campaign of Jinhua and Wangdu, respectively. The contributions of BrC aerosol light absorption of PM_2.5 at 405nm were 9.8% and 22.3%, and 5.9% and 15.2% at 532nm in Jinhua and Wangdu, respectively. The results indicate that the contribution of brown carbon to the aerosol light absorption at shorter wavelength is not negligible in China.

Key words： brown carbon (BrC) black carbon (BC) light absorption absorption angstrom exponent (AAE)
