Abstract: Middle East is one of the most aerosol subjected region of the world. The records of aerosol optical depth (AOD) from 2003 to 2016 inclusive are investigated standard aerosol optical depth index (SAODI) providing verbal and numerical interpretations about the AOD records at Syria-Iraq northern, west Iraq, Iraq marshes, Iran Ahwaz and Ilam regions in addition to Saudi Arabia and United Arab Emirates. AOD records at different countries have different probability distribution functions (PDF), and the criteria of the average AOD plus 1, 2, 3 and 4 times the standard deviation of AOD record methodology as available in the literature does not provide a common footing for AOD assessment. Application of innovative trend analysis of the aerosol records indicated that although trends have rather small slopes, but in the Marshes, Ahwaz and Ilam locations there are decreasing trends, whereas in other locations the trends have increasing tendency.
