Laser-assisted trace gas pollution measurement techniques
ABSTRACT
Various trace pollutant gases, greenhouse gases and volatile organic compounds emitted from power plants, biogas plants and various industries are essential considering their adverse effect on urban atmospheric pollution, environment and health. Detection and monitoring of these pollutants in the atmosphere is essential in reducing total emissions and improving urban air quality. Laser-based optical techniques allow non-contact, remote measurements of pollutant gases and emissions with high selectivity and sensitivity. Various optical-based methods will be discussed to monitor and sense trace gases, such as CO2, CH4, NH3, H2S, water vapor, etc. Recent advances in light detection and ranging (LIDAR) and point-measurement techniques will be discussed.
