Description
Summary:The transfer of selective radiation from exhaust flames and traces of air carriers is considered taking into account an acute selection of radiation spectra and radiation absorption spectra by the atmosphere. Numerical simulation of radiation transfer reveals the effects of medium clarification or enhancement of radiation absorption by it, depending on the temperature field and chemical composition of selective radiation sources created by airborne materials in the atmosphere. The effect of the temperature shift of the centers of spectral lines at high temperatures of the air carrier flame on the transfer of their radiation in the atmosphere is noted.
