Short summary

We compiled a ship emission inventory based on automatic identification system (AIS) signals in the Jiangsu section of the Yangtze River. This ship emission inventory was compared with Chinese bottom-up inventories and the satellite-derived emissions from TROPOMI. The result shows a consistent spatial distribution, with riverine cities having high NO_x emissions. Inland ship emissions of NO_x are shown to contribute at least 40 % to air pollution along the river.
