摘要
文章介绍和讨论了傅里叶变换红外光谱法(FTIR)在大气环境下被动遥测热烟羽中污染气体的原理及相关技术;提出了辐射光谱、测量区域内大气透过率谱的算法模型,以及应用非线性最小二乘拟合算法实现气体浓度反演的方法。实际遥测了工厂燃煤锅炉烟囱排放的污染气体,对SO2和CO2气体浓度进行了定量分析。实验结果表明该技术在工业烟囱及其他燃烧源污染排放的应急监测方面具有极大的应用前景。
The principle and techniqucs of passive remote sensing of gaseous pollutant in heated plume was illustrated and discussed in this paper. The algorithm of radiance spectra and transmittance spectra in measured region was proposed, and the method of retrieving gas concentrations with NLLS fitting algorithm was also proposed. The remote servicing of actual gaseous pollutant of srnokestack was done, and the quantitative analysis of SO2 and CO2 was completed.
