Abstract
Three-day HYSPLIT back trajectories indicate that ozone levels are typically about 17% lower in the 6-12Â km range under wind flow conditions from the East than in cases when trajectories came from the Mediterranean. High pressure may lead to subsidence of ozone from the upper troposphere/lower stratosphere and eventually cause an increase of ozone mixing ratios by â¼18% above average between 6 and 7Â km, i.e. slightly above subtropical subsidence layer. Under the impact of regional convective activity and associated lightning, ozone mixing ratios can increase by more than 35% averaged over the 9-12Â km altitude range. In both cases maximum ozone in the mid to upper troposphere reached more than 100Â ppbv.
