Inversion Algorithm of Vertical Visibility Based on Laser Detection

Visibility has always been one of the main contents of meteorological observation[1]. Currently, there are various types of products for detecting visibility under different conditions, but none of them can detect vertical visibility. The vertical and horizontal distribution characteristics of the atmosphere are different, and there is a great demand for detecting vertical visibility in some practical applications[2]. This article analyzes the vertical distribution characteristics of atmospheric aerosols, uses LiDAR to detect the backscatter signal profile of atmospheric aerosols, inverts and calculates the backscatter signal profile, and obtains the atmospheric extinction coefficient. Firstly, it proposes to use the backward recursive method to calculate the vertical visibility value, and conducts detection experiments.
