Abstract

During the 18-month Central Asian Dust Experiment we conducted continuous lidar measurements at the Physical Technical Institute of the Academy of Sciences of Tajikistan in Dushanbe between 2015 and 2016. Mineral dust plumes from various source regions have been observed and characterized in terms of their occurrence, and their optical and microphysical properties with the Raman lidar PollyXT. Currently a new container-based lidar system is constructed which will be installed for continuous long-term measurements in Dushanbe.

Highlights

  • Mineral dust from Central Asia is one of several major contributors to global aerosol

  • The idea of two new permanent Polly-NET stations in the eastern Mediterranean and Central Asian dust regions was born, which led into the project to install two PollyXT lidar systems in Cyprus and Tajikistan (PoLiCyTa)

  • In this presentation we want to summarize some results from the Central Asian Dust EXperiment (CADEX) campaign and present the current status of the new permanent lidar system in Dushanbe

Summary

Introduction

Mineral dust from Central Asia is one of several major contributors to global aerosol. The Central Asian Dust EXperiment (CADEX) was initiated in which in-situ and remote lidar measurements of dust over Dushanbe were performed from 2015 to 2016 in a statistical manner [1, 2]. The idea of two new permanent Polly-NET stations in the eastern Mediterranean and Central Asian dust regions was born, which led into the project to install two PollyXT lidar systems in Cyprus and Tajikistan (PoLiCyTa).
