The Aerosols Optical Thickness (AOT) and rainfall are important factors in the physical processes that occur in the atmosphere, such as absorption and dispersion of solar radiation and precipitation composition, and thus affect the radiation balance and water balance in the atmosphere. The methods used in the study depend on the monthly and yearly mean of the aerosol and sum of rainfall, taken from the European Mediterranean Weather Forecast (ECMWF) during the time period (2008-2018), for selected stations in Iraq (Mosul, Baghdad, Rutba, Basra). The largest value of the aerosol index was recorded in Basra, and the lowest value was recorded in Mosul the highest value of rainfall recorded in Mosul, and the lowest value in Basra. The relationship between the aerosol index and rainfall is a ten-year inverse relationship for the selected areas (Mosul, Baghdad, Rutba, and Basra).
