For the first time, we investigated the highly time-resolved chemical characterization, sources and evolution of atmospheric submicron aerosols at a regional background site in the North China Plain (NCP) using an Aerodyne high-resolution time-of-flight aerosol mass spectrometer and evaluated the seasonal differentials of photochemical and aqueous-phase processing on SOA composition and oxidation degree of OA. The results will help to understand air pollution in the NCP on a regional scale.
