Abstract. Multiple regression analyses of both global satellite data available since 1979 and ground-based (ozonesonde and Umkehr) data have been used to estimate the solar cycle variation of ozone in the stratosphere. A maximum percent ozone solar response occurs in the upper stratosphere; a weak or negligible response occurs in the tropical middle stratosphere and a secondary positive response occurs in the tropical and subtropical lower stratosphere. The latter response provides the main contribution to the solar cycle variation of total ozone, which also occurs primarily in the tropics and subtropics. We discuss differences between these results and model predictions. Possible explanations for the observed altitude dependence appear to require solar UV-induced effects on dynamical processes in the lower stratosphere.
Introduction
One proposed mechanism by which solar variability may influence tropospheric climate involves solar UV-induced
