Description
Lidar ozone data have been shown to be very accurate in the range 15 – 25 km. Long-term lidar records are thus ideal data sets to cross-validate satellite ozone records in the lower stratosphere. In this study, we use lidar ozone records spanning more than 20 years from five lidar stations, e.g. Hohenpeissenberg (Germany), Haute-Provence (France), Table Mountain (USA), Mauna Loa (Hawaï, USA) and Lauder (New Zealand) in order to assess satellite records obtained in the vicinity of the stations and retrieve long-term ozone trends in the lower stratosphere. The study includes an evaluation of the seasonality of the retrieved ozone trends at the various stations.
Key words: ozone trends, lower stratosphere, lidar, satellite observations
