Short summary
Regional transport is a systemic environmental challenge governed by multiple processes. Observations from a unique 528-m tower in Beijing reveal that aerosols vary among air masses originating from different directions, influenced by regional emission sources and reactions during transport. A comparison of pollutants between the 528-m layer and ground level confirms that transported pollutants are mixed down to the surface during daytime, governed primarily by planetary boundary layer process.
