| Abstract: | Scattering coefficient is one of the most important parameters of the aerosol optical properties. A kind of integrating nephelometer for measuring scattering coefficient is developed to investigate the aerosol optical properties.Principles and the system design of the system are presented,the optimal design of the optical chamber and the light source are proposed.Experimental results show that the correlation coefficient between scattering coefficient measured by the nephelometer and visibility measured by the forward-scattering visibility sensor was 0.834.It illustrates that the system is compact,low cost and reliable. |
