Dust storms cause major problems for human societies in arid and semi-arid
regions. This phenomenon involves the transport of suspended particles in the
atmosphere, often over long distances. In this study, MODIS data and WRFChem and HYSPLIT models were used to investigate aerosol optical depth
(AOD) during a dust storm affecting Iran from December 16 to 20, 2016. The
results showed that the output of the HYSPLIT model in the forward method
for December 16, 201,6, at 12 UTC, showed that the particles originating from
this section, including the Jazmurian region, mainly moved south during this
period. Also, the results showed that the AOD values in the south of Sistan and
Baluchistan province and the border between Afghanistan and Pakistan, west of
the Oman Sea, and east of the Persian Gulf show a significant increase compared
to before. Also, the amount of this quantity has increased for the Jazmurian
region and has reached 0.8 in some areas.
