Abstract

Aviation attributed nitrogen oxide (NOx) emissions lead to an increase in ozone and a depletion of methane. In this study we investigate the impact of weather related transport processes on these induced composition changes. Subsidence in high pressure systems leads to earlier ozone maxima due to elevated temperatures. Background NOx and hydroperoxyl radicals limit the total ozone change during summer and winter, respectively. High water vapor concentrations lead to a high methane depletion.
