Calculated surface temperature changes, ΔT 8 , due to stratospheric ozone depletion (at 35°N latitude in April) are less than previously estimated and range between –0.6 and +0.9°K. The sign of ΔT 8 is determined by the surface albedo and the presence or absence of a low-lying particulate layer (heating with particles, cooling without particles). The calculations indicate that a 90 percent stratospheric ozone depletion does not cause the temperature inversion at the tropopause to vanish, although it is weakened substantially.
