Experimental techniques for the calibration of lidar depolarization channels in EARLINET

Experimental techniques for the calibration of lidar depolarization channels in EARLINET

Particle depolarization ratio retrieved from lidar measurements are commonly used for aerosol-typing studies, microphysical inversion, or mass concentration retrievals. The particle depolarization ratio is one of the primary parameters that can differentiate several major aerosol components but o...
