Abstract

The Improved Limb Atmospheric Spectrometer on board the Advanced Earth Observing Satellite first detected the onset of denitrification in the 1996/1997 Arctic winter stratosphere. Box model calculations along back trajectories are used to estimate the degree of denitrification caused by the formation of nitric acid trihydrate (NAT) particles followed by their growth and sedimentation. The calculated loss of reactive nitrogen explains well the observed loss, identifying the mechanism of large NAT particle formation causing Arctic denitrification.
