Dust aerosols have serious influences on different sectors such as the economy, climate change, pollution, transportation and public health. Dust storms have increased over the Middle East especially impacting central Iraq lately. The goal of the work is to identify possible dust sources and pathways influencing the study area. Using remote sensing data by employing the monthly average of Aerosol Index (AI-OMI), HYSPLIT model and MODIS satellite to examine potential dust storms sources and their transport pathways through spring season in 2012. The results of aerosol index (AI) values by OMI s...

Abstract In the previous three decades, environmental and climatic systems have experienced considerable changes. These changes have probably influenced dust events in different areas in the world. Iraq represents one of the exposed regions to dust events. The study aims to (i) describe the spatialtemporal patterns of aerosol index values and dust events variability over Iraq using remote sensing data (AI-TOMS and OMI data with climate factors) and dust observations (suspended dust, rising dust and dust storms), (ii) identify the potential sources and transport pathways of dust storms over Ir...
