Abstract :
Alignment of the laser beam and telescope axes is crucial to the acquisition of high quality lidar data. For a continuously operated Mie lidar, a routine alignment correction is needed to ensure that its data are not influenced by the misalignment and thus truly represent the aerosol and cloud behavior. This paper describes the operation of such a lidar system with automatic correction of optical alignment.
