Paper Abstract

Recent conferences have discussed both active and passive FTIR remote sensing. However, the importance of the agent cloud temperature has not been discussed. A passive radiation model was developed that includes the effect of the agent cloud temperature. This model was compared with Beer's law as a function of temperature difference and concentration pathlength. The error in the absorbance calculated with Beer's law increases with decreasing temperature difference and with increasing concentration pathlength. The applications of the model include passive algorithm development and synthetic data production.
