Abstract

We present an intense dust transport event occurred over Athens, Greece during the BIOSPHERE campaign in summer 2023. Three multi-wavelength lidar systems have been used to provide the vertical profiles of the aerosol optical properties, and relevant mass concentration, together with temperature profiles, for the case of 13 July 2023. The dust load presence was responsible for the reduction of the UVB radiation at ground of the order of 5-10%.
