Modeling of the partitioning of reactive odd nitrogen in the lower stratosphere using aircraft measurements of NOy, NO, and other trace species

Abstract

The objective of this research was to gain a more thorough understanding of the atmospheric processes which control the partitioning of species within the reactive nitrogen (NO(y)) reservoir in the lower stratosphere. This understanding is crucial to predicting ozone loss in the stratosphere. NO(y) is defined as NO + NO2 + HNO3 + N2O5 + ClONO2 + HO2NO2 + NO3 + particulate nitrate. The research focuses on deriving the partitioning among these species using the combined set of measurements from the NASA ER-2 aircraft during recent missions designed to study stratospheric ozone depletion
