چکیده

A lidar system, incorporating tunable dye lasers and a 25-cm diam Newtonian telescope, has been constructed and applied in atmospheric pollution monitoring. The system, which is fully controlled by a specially designed microcomputer, has been used in several field tests, where stack effluents as well as the ambient air have been monitored. Results from particle, NO(2), and SO(2) measurements are discussed.

Atmospheric atomic mercury monitoring using differential absorption lidar techniques.

Three-dimensional mapping of atmospheric atomic mercury has been performed with lidar techniques, to our knowledge, for the first time. Industrial pollution monitoring, as well as measurements of background concentrations, is reported. High-efficiency frequency doubling of narrowband pulsed dye laser radiation was employed to generate intense radiation at the mercury UV resonance line. Field me...

System Simulation of Spaceborne and Airborne High Spectral Resolution Lidar for Aerosol Monitoring

Atmospheric aerosols play very important roles in climate change and air particulate pollution. Due to their highly variable optical and physical properties as well as to short atmospheric lifetimes and large spatial and temporal gradients, the aerosol impact on climate models and air pollution is really a complex task. Lidars based on elastic scattering have been largely used to measure aeroso...

LIDAR for Atmospheric Measurement and Probing

This paper describes a LIDAR for atmospheric measurement and probing (LAMP). The LAMP system is a commercial LIDAR unit that uses the design of boundary layer LIDAR (BLL), an optical radar technology developed at the National Atmospheric Research Laboratory (NARL) for atmospheric applications. The LAMP technology is useful for remote monitoring of atmospheric particulate and clouds in the tropo...

Application of the method of decomposition of lidar signal-to-noise ratio to the assessment of laser instruments for gaseous pollution detection

A general methodology for rating both performance and potential of lidar systems used for detection of atmospheric trace constituents including pollutants and gas leaks is developed. By individually examining and decomposing the contribution of both lidar system parameters and atmospheric operating conditions on signal-to-noise-ratio, a generalized figure of merit, V , for lidar quality is intr...

Scanning Lidar Based Atmospheric Monitoring for Fluorescent Detectors of Cosmic Showers

Measurements of the cosmic-ray air-shower fluorescence at extreme energies require precise knowledge of atmospheric conditions. The absolute calibration of the cosmic-ray energy depends on the absorption of fluorescence light between its origin and point of its detection. To reconstruct basic atmospheric parameters we review a novel analysis method based on twoand multi-angle measurements perfo...
