THESEO Fifth European Workshop on Stratospheric Ozone

27 Sept. - 1 Oct. 1999

St. Jean de Luz, France

The Fifth European Workshop on Stratospheric Ozone is being organised by the European Commission, CNRS and CNES.

The results of recent research on stratospheric ozone carried out in Europe in the frame of Environment and Climate programme of EC / DGXII and national programmes will be presented. In particular the findings of the Third European Stratospheric Experiment on Ozone (THESEO) which is investigating the ozone decline over middle latitudes, including Europe, will be discussed. Topics of interest include the chemistry and dynamics of the mid-latitude stratosphere, the links with processes occurring in the tropics, the Arctic and the upper troposphere, observed and modelled ozone loss, microphysical processes and heterogeneous chemistry.

As in the previous European workshops on stratospheric ozone, the presentation and discussion of results in poster sessions will be a major component. The oral plenary sessions will be a mixture of invited and selected presentations. The proceedings will be published by the European Commission in a volume containing extended abstracts of the oral and poster presentations.
