Particulate matter PM is a mixture of airborne liquid droplets and solid particles. The health concerns associated with PM less than 2.5 micrometers in diameterPM2.5, include both short and long-term health effects such as asthma, bronchitis,cardiopulmonary disease, cancer, and premature death. One source of PM2.5 is open burning i.e. burn pits, which is often the primary means of disposing of solid waste during military operations in combat zones to include Iraq and Afghanistan. Another source of PM2.5 is geological material natural windblown dust, which is common in arid environments. Past research has shown a relationship between PM2.5 and, meteorological data, geographic location, and aerosol optical depth AOD a measure of how much sunlight is absorbed or scattered by aerosols in a vertical column of air. This study looked at the association between PM2.5 and meteorological conditions and AOD at Bagram Airfield BAF, Afghanistan using data obtained from the U.S. Army, U.S. Air Force, and the National Aeronautics and Space Administration NASA.
