Abstract EN
The vertical structure of aerosol optical and physical properties was measured by Lidar in Eastern Kyrgyzstan, Central Asia, from June 2008 to May 2009.
Lidar measurements were supplemented with surface-based measurements of PM2.5 and PM10 mass and chemical composition in both size fractions.
Dust transported into the region is common, being detected 33% of the time.
The maximum frequency occurred in the spring of 2009.
Dust transported to Central Asia comes from regional sources, for example, Taklimakan desert and Aral Sea basin, and from long-range transport, for example, deserts of Arabia, Northeast Africa, Iran, and Pakistan.
Regional sources are characterized by pollution transport with maximum values of coarse particles within the planetary boundary layer, aerosol optical thickness, extinction coefficient, integral coefficient of aerosol backscatter, and minimum values of the Ångström exponent.
Pollution associated with air masses transported over long distances has different characteristics during autumn, winter, and spring.
During winter, dust emissions were low resulting in high values of the Ångström exponent (about 0.51) and the fine particle mass fraction (64%).
Dust storms were more frequent during spring with an increase in coarse dust particles in comparison to winter.
The aerosol vertical profiles can be used to lower uncertainty in estimating radiative forcing.
