Wang, W.-C., J.P. Pinto, and Y.L. Yung, 1980: Climatic effects due to halogenated compounds in the Earth's atmosphere. J. Atmos. Sci., 37, 333-338, doi:10.1175/1520-0469(1980)037<0333:CEDTHC>2.0.CO;2.

Using a one-dimensional radiative-convective model, we perform a sensitivity study of the effect of ozone depletion in the stratosphere on the surface temperature. There could be a cooling of the surface temperature by ~0.2 K due to chlorofluoromethane-induced ozone depletion at steady state (assuming 1973 release rates). This cooling reduces significantly the greenhouse effect due to the presence of chlorofluoromethanes. Carbon tetrafluoride has a strong ν₃ band at 7.8 micron, and the atmospheric greenhouse effect is shown to be 0.07 and 0.12 K (ppbv)^-1 with and without taking into account overlap with CH₄ and N₂O bands. At concentration higher than 1 ppbv, absorption by the nu₃ band starts to saturate and the greenhouse effect becomes less efficient.
