| Abstract: | 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. |
