Abstract
The long-held belief that atmospheric transmittance is only related to atmospheric conditions has served as the foundation for all the research in this field. However, there is a constraint to the idea that ground impacts are neglected to simplify the calculation process. The study demonstrated that atmospheric transmittance is controlled by not only the atmosphere itself but also by the spectrum distribution of radiated energy from ground materials. Following an examination of this constraint, the deviation theory of atmospheric transmittance might potentially explain the effect of radiated energy dispersion from various ground materials. Based on this theory, a mathematical model of the deviation was developed to further analyze the impact of the radiated energy distribution from different ground materials on the atmospheric transmittance and explore the emissivity distribution when the transmittance reaches an extreme value. The results indicated that in extreme circumstances, the distribution of emissivity maintained a certain regularity, providing a new approach for controlling a regional thermal environment. The research presented in this paper extends the current scope of knowledge in this field.
