Third European Stratospheric Experiment on Ozone (THESEO)
- THESEO is taking place during 1998 and 1999. The main aim is to improve our understanding of the causes of ozone depletion over Europe and other mid-latitude regions, where the ozone layer has been progressively depleted for the last 20-30 years.
