Short summary

This study evaluates the role of past emissions on the particulate matter pollution over Central Europe. It uses a chemical transport model along with a novel method of tagging emission according to the day they have been emitted. Our result showed that while the particulate matter pollution in cities is predominantly caused by actual day emissions, emission from day-1 to day-3 can also add a considerable fraction and under special circumstances even week old emissions can be important.
