Remote monitoring of air pollution by laser systems in airport environs
Abstract
A comprehensive study was performed to determine which laser systems could be most effective in the airport environment with respect to meeting the requirements of the National Ambient Air Quality Standards. It was found that of the different laser methods under development for measuring gaseous pollutants only the DAS (differential absorption by scattering) and LPT (long path transmission) methods appear to be useful, while the Raman scattering and fluorescence methods do not have sufficient sensitivity and are therefore range-limited. The advantages and disadvantages of the DAS and LPT methods are discussed in detail.
