N2 - The main findings are as follows: 1) stratus clouds provide significant protection from ultraviolet radiation exposure, but while stratospheric aerosols imply increased UVB exposure, 2) a redistribution of ozone from the stratosphere to the troposphere tends to decrease UV exposure, 3) a 20% ozone depletion leads to about 0.4 K/d cooling in the lower stratosphere, while redistribution of ozone from the stratosphere to the troposphere implies a warming of about 0.015 K/d in the upper troposphere; 4) stratus clouds may cause a large warming in the middle and upper stratosphere (0.8 K/d), 5) clouds have little effect on ozone photolysis leading to O(1D) production at altitudes higher than 25 km, 6) for ozone photolysis leading to O(3P) production photolysis rates may increase by 50% or more throughout the atmosphere due to multiple scattering by stratus clouds. -from Authors
