Abstract
Nitrogen oxides (NOy) are key oxidative species within the nocturnal atmosphere, due to reduced OH mixing ratios during nocturnal hours. NOy species have also been found to serve as a source of radical production in the early morning. When coupled with their impact upon air quality and climate, the study of NOy serves as important undertaking in the understanding of both night and daytime atmospheric processes. Two separate datasets were collected over the course of this research using Differential Optical Absorption Spectroscopy. In the first study NO3 vertical column densities (VCD) determined using lunar DOAS were analysed in conjunction with surface mixing ratios found using active DOAS on two separate nights during the summer of 2015 in order to quantify the NO3 vertical profile present at York University.
