Abstract

Dust orientation is an ongoing investigation in recent years. Its potential proof will be a paradigm shift for dust remote sensing, invalidating the currently used simplifications of randomly oriented particles. Vertically resolved measurements of dust orientation can be acquired with a polarization lidar designed to target the off-diagonal elements of the backscatter matrix which are nonzero only when the particles are oriented. We constructed the “WALL-E” lidar system emitting linear and elliptical polarized light and detecting various states of polarization of the backscattered light. Herein we present measurements of oriented rain, ice, and dust or drizzle particles acquired in Athens, Greece, during the preparation of the system for the ESA Aeolus Cal/Val Campaign “ASKOS” at Cabo Verde (June 2022).
