This paper presents a discussion of applications of metal-vapor lasers in lidar sounding of atmospheric aerosol. In particular, it is shown that data on the aerosol size spectra which are obtained with a metal-vapor-lasers-based lidar allow one to correct simultaneously acquired data on the ozone density profiles for the atmospheric aerosol. A stationary Cu-vapor-based lidar for detecting spatial distribution of industrial aerosols in the atmosphere over an industrial center is described.
