Observational data of Atmospheric Chemistry

We perform intensive field campaigns/long-term observations at selected sites in East Asia. We observe concentrations of ozone, its precursors, and aerosol chemical species, as well as aerosol optical parameters. We evaluate model simulations (and thus emission inventories) and perform process analyses for the causes of the variability (e.g., transportation and transformation, ozone production rate and regimes). Aerosol mass closure and chemical-physical-optical point closure are also our focus.
