Abstract
The effect of varying ozone column density on radiative-photochemical relaxation is examined. It is shown that neglecting variations in the total number of ozone molecules between a particular level and the sun can result in a spurious 50% increase in the damping rate of temperature perturbations. The relaxation rate of ozone perturbations, on the other hand, is decreased by as much as 50% if variations in extinction are neglected. The distribution and magnitude of the effect of varying column density on radiative-photochemical relaxation depends on elevation, latitude and season.
