Abstract: Abstract Over recent decades, dust storms have had a severe impact on the Middle East at the local and regional scales. Remote sensing is a feasible method for exploring dust storm sources, and this study utilized SeaWiFS satellite data and GIS modeling to investigate the issue in the region. Aerosol optical depth was used as an indicator to detect dust events and identify sources. The results revealed an increase in dust sources in some areas of Iraq, Saudi Arabia, and Oman in recent years, while the situation remained stable in eastern neighbors. Four main areas were identified as high-intensity dust producers: the northern part of Iraq near Mosul and Baghdad, the common border of Kuwait, Saudi Arabia, and Iraq, the southeast of Saudi Arabia and the western border of the UAE, and the middle of Oman. To validate the results, the study used 35 AERONET ground stations, including 608 comparative data. The achieved results showed a correlation coefficient of 0.75 and RMSE error of 8.6% between the AERONET stations and the findings of the study. These results provide valuable insights into dust storm sources and trends in the Middle East, which can inform efforts to mitigate their impact on the region.
