Short summary

In this study, we investigated short time variability of NO_x emissions and lifetimes on a global scale. We combined 2 years of satellite Sentinel-5P TROPOMI tropospheric NO₂ column data with wind data. Fifty NO_x sources distributed around the world are analyzed. The retrieved emissions show a clear seasonal dependence. NO_x lifetime shows a latitudinal dependence but only a week seasonal dependence. NO_x emissions show a clear weekly pattern which in contrast is not visible for NO_x lifetimes.
