Dust transports cause significant
increases in atmospheric concentration and surface PM10 particulate matter. In
recent years, Asian countries have experienced dust transport frequently. Dust
transport has a significant negative impact on human health, the economy and
the environment. This study includes the analysis of source regions and dust
transport dated in 27-29 May 2018 over Turkmenistan. In the study, a general
dust situation of Turkmenistan region has been studied by using MODIS AOD data.
Then, the meteorological conditions and the pathway of this dust transport
event on were examined. The preliminary analysis using synoptic analyzes and
satellite data showed that the dust transport is coming through Uzbekistan and
Kazakhstan. The transport took place on the south direction and affected most
of Turkmenistan on 27 May 2018. Observed AOD data in the region increased
significantly and took its maximum on 27 May 2018. The effect of this movement
in Turkmenistan lasted until 30 May 2018. The global CAMS dust model has
generally estimated dust transport event even some overestimations. MSG/RGB
satellite products were examined detailly in order to analyze the source
regions of this dust transport. The analyzes showed the main source region of
this dust transport as Aral lake.
