  author={Ann Louise Sumner and Paul B. Shepson},
The oxidative capacity of the atmosphere determines the lifetime and ultimate fate of atmospheric trace species. It is controlled by the presence of highly reactive radicals, particularly OH· formed as a result of ozone photolysis. The dramatic depletion of ozone in Arctic surface air during polar sunrise, therefore offers an opportunity to improve our understanding of the processes controlling ozone abundance and hence the oxidative capacity of the atmosphere. Ozone destruction is catalysed by… CONTINUE READING
