Atmospheric Pollution Monitoring Using Laser Lidars

摘要: Advanced techniques are needed to monitor our threatened environment, evaluate pollution levels and developmental trends. While tropospheric has obvious manifestations in terms of health problems, water soil acidification, forest damage, human-induced stratospheric changes the ozone layer, as evidenced by occurrence “ozone holes” at polar caps, may have much more far-reaching consequences1−6. Laser spectroscopy provides powerful means for remote sensing molecules atmosphere, yielding information on well meteorological conditions. There two major kinds laser methods applicable sensing7–15: 1) Long path absorption monitoring; and, 2) Lidar (Light detection ranging), with subdivisions: Fluorescence lidar Raman scattering lidar Mie lidar Differential lidar (DIAL).
