Dust transports cause significantincreases in atmospheric concentration and surface PM10 particulate matter. Inrecent years, Asian countries have experienced dust transport frequently. Dusttransport has a significant negative impact on human health, the economy andthe environment. This study includes the analysis of source regions and dusttransport dated in 27-29 May 2018 over Turkmenistan. In the study, a generaldust situation of Turkmenistan region has been studied by using MODIS AOD data.Then, the meteorological conditions and the pathway of this dust transportevent on were examined. The preliminary analysis using synoptic analyzes andsatellite data showed that the dust transport is coming through Uzbekistan andKazakhstan. The transport took place on the south direction and affected mostof Turkmenistan on 27 May 2018. Observed AOD data in the region increasedsignificantly and took its maximum on 27 May 2018. The effect of this movementin Turkmenistan lasted until 30 May 2018. The global CAMS dust model hasgenerally estimated dust transport event even some overestimations. MSG/RGBsatellite products were examined detailly in order to analyze the sourceregions of this dust transport. The analyzes showed the main source region ofthis dust transport as Aral lake.
