International Conference on Ozone in the Lower Stratosphere

An International Conference on Ozone in the Lower Stratosphere will take place in Halkidiki, Greece, on 15-20 May 1995. It is jointly organized by the Commission, NASA, WMO, NOAA and IOC/IAMAP.

The conference will focus on the study of ozone depletion, particularly in the lower stratosphere in both hemispheres. The emphasis will be on the interpretation of new measurements, key uncertainties and critical chemical and dynamical processes.

In particular, the following topics will be discussed:

- Ozone trends (tropics, mid-latitudes, and polar, total ozone and profile);
- Aerosol observations and interpretation;
- NOy observations, interpretation and sources (including chemical partitioning and sources);
- HOx observations, interpretation and sources;
- CIOx observations, interpretation and sources;
- Transport and dynamics;
- New chemistry (including laboratory and modelling studies of new gas-phase or heterogeneous chemistry);
- Radiation (including climate coupling and radiative budget).
