Source data for atmospheric Cl/BrPAH concentrations, phase partitioning, and city-level ClPAH predictions

This dataset contains the source data underlying the main-text figures of a study on the occurrence, phase partitioning, size distributions, and spatiotemporal variability of atmospheric chlorinated and brominated polycyclic aromatic hydrocarbons (Cl/BrPAHs) in Europe and China. The Excel files correspond to the individual main-text figures and include measured gas- and particle-phase Cl/BrPAH concentrations, congener profiles, particle-size distributions, and model-derived gaseous and particle-phase ClPAH concentrations for 168 Chinese cities in 2015, 2017, 2019, 2021, and 2023. Individual worksheets are labelled according to the corresponding figure panels. Variable definitions and units are provided within each file.
