Abstract:A compact aerosol lidar working with direct detectio n is introduced.It is used to measure atmospheric aerosols and clouds.The struct ure of this system and its working principle are illustrated.The horizontal rec eived signal of this lidar is analyzed and processed in detail,and its geometri c overlap factor is gotten.With a further processing,the horizontal atmospheri c extinction coefficient and the corresponding horizontal atmospheric visibility are gained.
Keywords:lidar  aerosol  geometric overlap factor  extinction coefficient  visibility
