Purpose:

• To propose a novel computer model for radiometric scene simulation of pollution clouds.
• To simulate spectra for complex environments, incorporating specific hazardous substances.
• To validate the model by comparing simulated results with experimental data.

Summary:

• A computer model was developed for radiometric scene simulation, generating spectra for pollution clouds in complex environments.
• The model introduces the spectral effects of hazardous pollutants, such as (CH3)2CHO(CH3)FPO and (CLCH2CH2)2S, into measured background spectra.
• The simulation utilizes passive Fourier transform infrared spectrometer (FTIS) data, and the model's simulated results show strong agreement with experimental findings.

Impact:

• Provides a validated tool for predicting and analyzing the spectral impact of hazardous pollution clouds.
