Abstract

Focusing on Tajikistan, a region facing critical environmental challenges, this extended abstract provides insights into the relationship between aerosols and clouds in Central Asia by means of lidar observations. Since 2019, a novel Dual-Field-of-View (DFOV) Raman polarization lidar system in Dushanbe has provided highly-resolved data on aerosol and cloud microphysical properties. Given the limited observational experiments in Central Asia, these measurements might play a crucial role in addressing climaterelated concerns. In fact, this technological deployment might not only provide a better picture regarding the spatio-temporal distribution of mineral dust and urban emissions, but also improve our understanding regarding the complex interactions between aerosol and clouds. One of the most uncertain aspects when predicting future temperature and precipitation patterns. Furthermore, an extended trajectory-based source attribution tool has been implemented to track air masses in Tajikistan, providing enhanced support for this and future studies. This research focuses on data evaluation and analysis, building upon established lidar methodologies. The resulting insights can potentially contribute to a better understanding of the relationship between aerosols and clouds in the dry continental conditions that persists in this region.
