    A new spectrometry is developed to obtain near-ground the optical parameters of atmospheric particles. The Active Differential Optical Absorption Spectroscopy (DOAS) system is developed to measure the optical parameters of atmospheric particles. Under the clean atmospheric condition, the reference optical path is designed to calibrate the system.The broad wavelength band xenon arc lamp is used to monitor the optical parameters of atmospheric particles as light source of differential optical absorption spectroscopy system. The model of optical depth is studied to retrieve the optical properties of atmospheric particles. The optical depth of atmospheric particeles, Angstrom turbidity coefficent, Angstrom wavelength exponent, and visibility were retrieved during the field campaign. Angstrom parameters were retrieved by log-linear regression. The total atmospheric absorption are measured to attain average regional concentrations basing on the active differential optical absorption spectroscopy system, which is more representative and applicable.
