Remote sensing of atmospheric gases and particulates by lidar
Abstract
It is pointed out that remote sensing techniques are emerging as an important means of monitoring the atmospheric effects of energy use. A description is provided of two optical radar or lidar (light detection and ranging) systems which are designed to measure remotely both gaseous and particulate pollutants. One of the two systems, the Airborne Lidar Plume and Haze Analyzer (ALPHA-1), is designed to measure particulate plumes and haze layers over large areas using an aircraft monitor. The other system, the Differential Absorption Lidar (DIAL), is ground-based and is designed to measure the distribution of gaseous concentrations in power plant plumes. Gases which can be measured include sulfur dioxide, ozone, and nitrogen dioxide. The lidar uses optical wavelengths to determine scattering from atmospheric constituents. The source of the optical energy is a laser.
