AB: AbstractϤThe effects of temperature and pressure, especially temperature on atmospheric absorption coefficients and then cooling rate are discussed in detail in this paper. Six approaches to deal with the effects are proposed in the framework of correlated -distribution. The atmospheric cooling rates calculated by these approaches are compared with that of line-by-line (LBL) integration and then a best method to consider the temperature effect is presented. It is also pointed out that although the effects of temperature on atmospheric absorption coefficients is of the second importance compared with the pressure effects, the effects of temperature on atmospheric cooling rate are very complicated and must be considered in the practical radiation computation.
