Abstract

Different regions of Iran are affected by internal or external dust sources. Satellite data can be used to investigate the temporal and spatial distribution and the detected source of dust. The aim of this study was to analyze the concentration of surface dust, dust in air column and aerosol optical depth (AOD) using MERRA-2 Model and Aqua Satellite data in Iran. Data were prepared between 2007 and 2017 and the figures were plotted by Grads and OriginPro software. The research findings showed three cross-border dust sources including western, eastern and northeastern Iran and two internal area in the Dasht Kavir and southeastern of Iran. The dust source located in southeastern Iraq and Kuwait have the highest concentration of surface dust. In Abadan, the highest concentration of surface dust with 552 (μ gm3⁄ ) in summer, dust in air column with 709 (mgm2⁄ ) and the AOD of MERRA-2 with 0. 58 in spring took placed. The correlation coefficient between surface dust and air column dust was obtained in internal area including Tabas, Kahnooj, Khor Biabank and Nikshahr with 0. 94, 0. 93, 0. 89 and 0. 89, which can indicate the effect of local conditions on dust development. Time series of air column dust in three stations of Bushehr, Abadan and Ahvaz shows the highest decreasing trend with-0. 05 and-0. 035, indicating reduction effect of dust external sources. In temporal distribution, the years of 2008 and 2012 were determined by the most severe and widespread dust in Iran. In monthly distribution, the maximum Dust Concentration were obtained in April and July 2008, May 2012 and July 2016 in Ahvaz.
