Paper Abstract

Retrieval method for aerosol mass concentration vertical distribution with Lidar is the one of research contents in environment monitoring fields, but little headway has been made. Making use of the extinction coefficients on ground gained by Lidar and corresponding mass concentrations gotten by TEOM, the relationship between extinction coefficient and mass concentration can be disclosed, then the mass concentration vertical distribution can be retrieved through the extinction coefficient vertical distribution. Based on it, two models are developed, and confirmed by some experiments. It is indicated that the aerosol mass concentration vertical distribution retrieved by both the models are consistent with each other, and consistent with fact. The models are maneuverable and simple, and can monitor online and real-time.
