This paper describes a mobile Differential Absorption LIDAR system, which operates in the ultraviolet, visible and infrared spectral regions. This system can measure a range of important air pollutants emitted by industry, including SO2, NO2, NO, HCl, benzene, toluene and a large range of other VOC's. These species can be monitored at fugitive and flammable levels at ranges of up to 1 km (for infrared measurements) and 3 km (for ultraviolet measurements). Examples of measurements of fluxes emitted from large scale industrial sites are presented and discussed.
Comparisons are given between measured fluxes and those calculated using the US Environmental Protection Agency's and American Petroleum Institute's standard procedures for estimating industrial emissions. The fluxes measured by DIAL are higher than the values derived from the API procedures. Possible reasons for discrepancies between the measured results and the EPA/API estimation procedures will be discussed.
