Objective
The project will establish a scientific basis for the detection of the earliest signs of ozone recovery due to Montreal protocol and its amendments. To achieve this we will select the best long-term data sets available on mid-latitude and polar ozone and study them using advanced multiple regression methods developed in this project. We also use the most up to date global meteorological data, ERA-40 (since 1957), to determine the dynamical changes and trends and asses their role in re-distribution of ozone in the NH-stratosphere in recent decades. ERA-40 will be also used to force the Chemical Transport Models to assess the relative roles of chemistry and transport in ozone changes. Finally, the synthesis of the key objectives will improve the attribution of observed ozone changes to anthropogenic influences and to the variations in a natural atmosphere, which, however, can be modulated by climate change.
