Evaluation of a commercial aerosol lidar scanner for industrial pollution monitoring

Resumen

In recent years, light detection and ranging (LiDAR) technology has gained popularity in various applications, including remote sensing of Particulate Matter (PM) absolute concentrations. Raymetrics PMeye is a unique platform consisting of a state-of-the-art scanning lidar, innovative algorithms and auxiliary sensors, used for large areas PM concentrations monitoring. Using a novel inversion scheme for transforming raw signals to aerosol concentrations, PMeye is one of its kind for aerosol monitor in urban or/and industrial areas. Measurements performed at a steel factory in Latin America, a highly variable area in terms of emission sources, support the effectiveness of the overall system. Measurements evaluation against a light scattering in situ PM counter, placed at major emission sources on various ranges and directions from the lidar, present high correlation and very low mean relative differences.
