| Abstract: | As a new tool to detect atmosphere, lidar can derive the value of visibility by directly collecting the scattered laser from the atmosphere. It makes lidar become a main instrument for measuring visibility. A 532nm-wavelength Mie lidar is being developed to measure atmosphere visibility. Specification of the lidar and the measuring method and algorithm for measurement are introduced. The results show that Mie lidar has high reliability through simulating with lidar parameter. The error of calculating for visibility is less than 16%. |
