Infrared radiative transfer model of pollution cloud and computer simulation of infrared spectra

The infrared radiative transfer model of pollution clouds is proposed. The infrared spectra of pollution cloud radiative transfer are studied through the proposed simulation model. Aiming at the established three-layer infrared radiative transfer model of pollution cloud, the infrared radiative spectra of the pollution clouds at different concentrations were simulated with the field background spectra (that are measured by Fourier transform infrared spectrometer) and every interferent radiative spectrum as the basic radiative data. The result shows that there are obvious spectrum characteristic peaks at the wave bands of 810cm-1，920cm-1 and 1040cm-1. The simulated spectra are consistent with the field experimental spectra, and the RMS error of the two spectra is only 1.0.
