Investigation of Aviation's Contribution to Tropospheric NOx-O3 Presence

As global air traffic has continued to grow over the past two decades, it has effectively led to a sharp increase in the emissions and corresponding global warming through the 'greenhouse gas effect'. Apart from CO2 and H2O, NOx is the next major aviation-emitted species which significantly contributes to climate change through its atmospheric chemistry leading to the formation of O3, which in itself is another major greenhouse gas. Since global air traffic is a major source of tropospheric NOx, this thesis analyzed the contribution of aviation to tropospheric mixing ratios of NOx and O3. The analyses were performed on 2 major aspects: (A) to identify and understand the seasonal & zonal patterns with respect to aviation's contribution to tropospheric mixing ratio of NOx and O3, and (B) to comprehend the differences between Perturbation & Tagging methodologies in estimating aviation's contribution to tropospheric mixing ratio of NOx and O3.
