  • The extinction character of sand and dust particles can cause the attenuation of visible and infrared light transmission.The optical characteristics of sand particle were calculated on the basis of the Mie theory,then the extinction coefficient was compared between sand blowing and normal weathers.The vertical optical characteristic distribution of the sand aerosol at 0.532μm,1.06μm and 10.6μm was provided according to the results measured with micro pulse lidar in Beijing.It is valuable for studying sand and dust blowing.

Abstract: The extinction character of sand and dust particles can cause the attenuation of visible and infrared light transmission.The optical characteristics of sand particle were calculated on the basis of the Mie theory,then the extinction coefficient was compared between sand blowing and normal weathers.The vertical optical characteristic distribution of the sand aerosol at 0.532μm,1.06μm and 10.6μm was provided according to the results measured with micro pulse lidar in Beijing.It is valuable for studying sand and dust blowing.
