Résumé des résultats (Abstract) (Anglais)

EUPLEX will critically test current hypotheses for the three key processes of arctic stratospheric ozone depletion chemistry:
1. PSC formation and properties in Lee-wave and synoptic scale PSC;
2. Halogen activation on PSC, and;
3. Chemical ozone loss.

Optimum chemica1 and microphysical information will be measured on dedicated flights of a suitably instrumented high-altitude research aircraft employing two new flight strategies:
1. Quasi-Lagrangian flights through Lee-wave PSC;
2. Multiple flights probing the same air masses twice within time periods of several days.

Comparison of these first-time observations and state of the art microphysical and chemical models will yield improved or new parameterisations or corroborate established concepts that are a prerequisite for numerical simulations ta predict the future state of the azone layer.
