Short summary
Aviation-attributed nitrogen oxide (NOx) emissions lead to an increase in ozone and a depletion of methane. 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 an enhanced chemical activity. Background NOx and hydroperoxyl radicals limit the total ozone change during summer and winter, respectively. High water vapour concentrations lead to a high methane depletion.
