Abstract
A new depolarization channel has been implemented in the BarcelonaTech University (UPC) multi-wavelength lidar system. The optical and mechanical designs are presented. The special configuration of the total power channel is also detailed, with the relevant aspects in measurement inversion. Some preliminary measurements are presented for Saharan dust intrusion events.

Summary
The capability of measuring depolarization of the backscattered light, together with multiwavelength detection, improves the ability of a lidar system to identify the aerosols present in the atmosphere, as it has been pointed out by different authors [1]–[4]. The BarcelonaTech University (UPC) Remote Sensing Lab (RSLab) has implemented a new depolarization channel for its lidar system. The depolarization channel has been tested with measurements during Saharan dust intrusion events taking place on May and June 2016
