The project IOANA proposes to better understand the intimate coupling between ozone mixing ratios and particulate nitrate isotopic characteristics. Ozone Depletion Events which occur in Arctic coastal locations shortly after sunrise are a subject of interest per se (scientifically challenging for two decades) but also provide a context in which ozone mixing ratios are highly variable, enabling to characterize the dynamic of correlation and process studies with a resolution of a day. This is a first step towards the use of the isotope tool in reconstructions of the oxidative capacity of the atmosphere. This programme is a preparation of the IPY-OASIS project and propose to coodinate a set of collaborations than will be effective duing the International Polar Year.
