Short summary
The VOC emission inventory has large uncertainties. An updated VOC emission inventory of vehicles in China was developed based on a set of state-of-the-art methods and big data. Exhausts and evaporation were taken into account. Our results narrowed the gap between inventories and the real emissions. Detailed speciation reveals the chemical characteristics of emissions, which has the potential to improve the understanding of atmospheric chemical processes in polluted regions.
