Using the atmospheric mode provided by LOWTRAN, a method for the quantitative analysis of the infrared spectral characteristics of contaminated clouds by passive Fourier transform infrared spectroscopy (FTIS) is given. The simulation results of infrared spectra of contaminated clouds and the detection limits of passive FTIS of several clouds are discussed in detail. The results show that they are important tools for quantitative assessment of passive FTIS detection performance and spectral discriminators.
