摘要
大气中的一些污染分子不仅威胁人类的生存环境 ,而且破坏地球上的生态平衡 .差分吸收光学光谱技术和差分吸收激光雷达可用于监测它们 .前者可以进行定点和局部测量 ,后者可进行远距离和大范围的遥感测量 .文章简要地介绍了差分吸收光谱技术和差分吸收激光雷达的原理和数学基础 。
Certain pollution molecules in the atmosphere are threatening the environment of mankind, and destroying the Earth′s ecological balance. Differential optical absorption spectroscopy (DOAS) and differential absorption laser radar (DIAL) can be widely used to monitor these molecules. DOAS is used in local measurements, and DIAL in remote sensing. We introduce the principles and mathematical foundation of DOAS and DIAL, then discuss in detail their application in the monitoring of atmospheric environmental pollution.
