Temporal and Spatial Analysis of Particulate Matter Concentrations in Iraq

Abstract Particulate Matter (PM) is microscopic particles of solid or liquid matter suspended in the air. The term aerosol commonly refers to particulate/air mixture, as opposed particulate alone. Sources can be natural anthropogenic. They have impacts on climate and precipitation that adversely affect human health, ways additional direct inhalation. statistical methods used this study depend daily, monthly, seasonal means PM 1 , 2.5 10 with data taken from European Center for Medium-Range Weather Forecasts (ECMWF) year 2021 at times 00.00 am, 12.00 pm over Rutba, Mosul, Basrah, Baghdad Stations. It has been shown μm more abundant atmosphere, especially Rutba station. a large vertical movement wide area thus leads an increase temperature formation convection currents. This type storm occurs within certain layer starting surface earth about 1.52 km. These storms are severe during day decrease intensity night. long-lasting last two weeks.
