The smog in China is a unique mixture of classical (SO2, soot) and photo-chemical (O3, VOC, NOx and secondary organic aerosol (SOA)) smog with implications for short lived climate pollutants (SLCP), secondary chemistry and aerosol properties. The aim of this project is to understand and resolve discrepancies in process descriptions affecting soot, SOA and O3. This knowledge is a prerequisite for efficient abatement strategies of the smog events in urbanised parts of China and in similar environments. The objectives will be fulfilled by joint research efforts exploring new knowledge on the above topics utilising state-of-the-art methods in field, laboratory and modelling studies. We will focus on two highly populated regions in China: the Beijing region and Pearl River Delta, which includes Hong Kong. We will characterise, illustrate and elucidate the exceptional photochemical smog events occurring in China and how the air pollution processes differ from other places. An assessment of current policies and how they can be improved using science-policy interplay will be carried out with focus on emissions affecting soot, SOA and O3. The proposed project builds on the strong research environments of the Gothenburg Atmospheric Science Centre (GAC) and its Chinese partners to address key issues concerning air quality in China. It will enable us to take a leading role in air pollution research and contribute to sustainable development in China and elsewhere.
