Abstract To achieve the on-line measurement of the broad-band extinction coefficient of atmospheric aerosols, an incoherent broad-band cavity enhanced absorption spectroscopy (IBBCEAS) experimental instrument was established. Then, in order to evaluate the accuracy and stability of the system, a comparative measurement was carried out simultaneously with CAPS-ALB, a single wavelength Cavity Attenuation Phase Shift ALBedo monitor, in the Environmental Science Building of Fudan University. The comparison result show that the measured aerosol extinction coefficients at the wavelength of 532nm of above two instruments has a same trend with a correlation coefficient of 0.974, indicating the established IBBCEAS system has similar reliability and stability to the metrological certificated high-precision instrument. After calibrated with CAPS-ALB, the measurement accuracy of the IBBCEAS system was significantly improved, and the measurement differency between the two instruments was reduced from 7.08Mm-1 to 2.4Mm-1. And it was also found that the broad-band spectral measurement is of great significance for studying the wavelength dependency of aerosol extinction coefficient.
