This phenomenon involves the transport of suspended particles in the atmosphere, often over long distances. In this study, MODIS data and WRF-Chem 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. https://sustainearth.sbu.ac.ir/article_105318_a1f421729e8e51150c007ba85891f529.pdf
