Uncertainty Assessment of Differential Absorption Lidar Measurements of Industrial Emissions Concentrations

Differential absorption lidar (DIAL) has been shown to be a very effective technique for the location and quantification of emissions pollutants greenhouse gases at industrial facilities. Several field trials have demonstrated DIAL system performances contributed development methodology, which is basis protocols described in European Standard EN 17628. While numerous papers focused on different aspects uncertainties, rigorous propagation uncertainties equation not found. In this study, all uncertainty sources contributing concentration measurement are assessed impact they calculation mass emission rate. We derive equations both path-concentration integral uncertainties. The results from methane presented, showing that signal noise ratio backscattered signals 500, standard 2.3 ppb km 92 over sampling spacing 45 m. An also presented enabling contribution rate uncertainty.
