Development of an airborne lidar for characterizing particle distribution in the atmosphere. Final report
A two-wavelength (0.53 and 1.06 ..mu..m) airborne lidar system was constructed and field tested. The ALPHA-1 (Airborne Lidar Plume and Haze Analyzer) was designed to observe smoke plume and atmospheric boundary layer particles over large areas. A data-processing system was designed for both real-time facsimile (gray-scale) display and magnetic tape recording. Multiple microcomputers were used to optimize processing capabilities within the power, weight, and size constraints of medium-sized twin-engine aircraft. A one-week field program was conducted to evaluate ALPHA-1 performance and reliability. The system successfully observed boundary layer structure over the Los Angeles area and the downwind structure of particulate plumes from the Navajo (Page, Arizona) and Four Corners (Farmington, New Mexico) power plants. Except for one system failure, ALPHA-1 performed very well on its first data-collection mission. The data show the importance of terrain features in establishing particle distributions over urban areas and downwind of large power plants.
