Fate of the nitrate radical at the summit of a semi-rural mountain site in Germany assessed with direct reactivity measurements

The reactivity of NO.sub.3 plays an important role in modifying the fate of reactive nitrogen species at nighttime. High reactivity (e.g. towards unsaturated volatile organic compounds - VOCs) can lead to formation of organic nitrates and secondary organic aerosol, whereas low reactivity opens the p...

Description
Summary:	The reactivity of NO.sub.3 plays an important role in modifying the fate of reactive nitrogen species at nighttime. High reactivity (e.g. towards unsaturated volatile organic compounds - VOCs) can lead to formation of organic nitrates and secondary organic aerosol, whereas low reactivity opens the possibility of heterogeneous NO.sub.x losses via the formation and uptake of N.sub.2 O.sub.5 to particles.
