The ReACT group of IAASARS has developed “WALL-E” lidar, a novel polarization lidar system capable of monitoring possible dust orientation and microphysical properties. WALL-E emits linearly- and elliptically-polarized light and detects the linear and circular polarization of the backscattered light from the dust particles in the atmosphere. It also employs scanning capabilities so as to provide more information on the dust orientation and microphysical properties. The system is designed based on the high quality standards of the European lidar network EARLINET, in the framework of ERC-COG program D-TECT.
