| Abstract |
The paper presents a new approach to quantifying emissions from fugitive gaseous air pollution sources. Computed tomography (CT) and path-integrated optical remote sensing (PI-ORS) concentration data are combined in a new field beam geometry. Path-integrated concentrations are sampled in a vertical plane downwind from the source along several radial beam paths. AN innovative CT technique, that applies the smooth basis function minimization (SBFM) method to the beam data in conjunction with measured win data, is used to estimate the total flux from an area source. A simulation study was conducted to evaluate the proposed methodology under two-beam geometry and configurations. This approach was found to be robust for a wide range of fluctuating wind directions. In the very sparse beam geometry examined (five paths), successful emission rates were retrieved over a 70-degree range of wind directions. |
