Dust influences climate and weather by direct and indirect radiative effects or heterogeneous ice nucleation. Dust is often transported to and across Tajikistan. Tajikistan and all other countries in Central Asia suffer from climate change and the potential role of dust in that climate change needs to be investigated and quantified. Therefore the Central Asian Dust EXperiment (CADEX) conducted first lidar observations in Tajikistan for long-term vertically resolved aerosol measurements with the multiwavelength polarization Raman lidar PollyXT from March 2015–August 2016. A measurement example of a polluted dust layer as well as mean values of intensive optical properties and the aerosol optical thickness measured during the months August 2015 and August 2016 are shown.
