Monitoring the vertical distribution of the aerosol with lidar is one of the focuses in the environment monitoring field.In order to study the vertical distribution of the air aerosol,a model to retrieve aerosol mass concentration was analyzed theoretic;aHy and proved experimentally.A modified model was presented based on exponent model and analysis of influence of the meteorological factors upon aerosol mass concentration.With the method of nonlinear least squares and some experience,some key parameters of the model and the vertical distribution of mass concentration can be retrieved.Conclusions are drawn as follows; the modified model can satisfactorily reflect the influence of meteorological factors upon aerosol mass concentration;the retrieved results consist with measured values.The results may be regarded as a reference to the research in this field.
