Abstract

The effect of aerosol microstructure on the estimation error of wind velocity measured by cw CO₂ Doppler lidar is analyzed in the paper. Based on the numerical simulation of a lidar return is has been shown that aerosol particles, due to their difference in size, make essentially different contribution to a measured lidar return power that leads to deviation of the lidar return statistics form the Gaussian one and results in the increase of the lidar estimation error of wind velocity, especially with small lidar probe volumes. With the increase of lidar probe volume the error of wind velocity estimation decreases. The values of the error variance (sigma) _e² calculated with the use of developed by authors algorithm of simulation of lidar return are in agreement with the experimental values of (sigma) _e² obtained under different longitudinal size of probe volume.
