This project is an observation of regional (Ozone) pollution as well as measurement of the various precursors leading to the formation of Ozone. Ozone is created when a chemical reaction between oxides of nitrogen (NOx) and volatile organic compounds (VOCS) takes place in the presence of sunlight. Ozone is a health problem as it can reduce lung function and harm lung tissue. These are risk factors for young children, the elderly, and those who suffer from diseases such as asthma. Ozone in the earth’s lower atmosphere (troposphere) can be formed from pollutants released into the air from car exhausts, refineries, and power plants to name a few. Throughout the day the surface air is mixed within the planetary boundary layer through convection as the Earth’s Surface heats up. In search of a solution to the regional air quality problem, various instruments such as LIDAR’s, trace gas analyzers, and Ceilometers are used to gauge ozone and aerosols. Our mission is to identify aerosols and the precursors of ozone, and the effect they have on down-wind areas such as Long Island, New York and Connecticut. We are also interested on how heat waves impact the regional air quality. With a better understanding of the air quality around us, we can help to promote cleaner and breathable air.
