摘要

摘要: 针对建立的三层结构污染云团红外辐射传输模型，采用实测场地背景和各种干扰物辐射光谱作为基本的辐射数据，对不同浓度的污染云团红外辐射光谱进行仿真。结果表明：利用实测场地背景辐射光谱和该模型仿真污染云团DMMP红外光谱，光谱在810cm-1，920cm-1和1040cm-1波段上有明显的特征峰。当模型考虑干扰物和背景辐射的变化影响时，污染云团在810cm-1，920cm-1和1040cm-1波段上的光谱特征明显减弱。仿真光谱与场地实测光谱有比较好的符合，两者的RMS误差约为1.0。

Abstract: 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.
