    Heterogeneous sulfate aerosol formation mechanisms during wintertime Chinese haze events: air quality model assessment using observations of sulfate oxygen isotopes in Beijing by J. Shao, J. Shao, Q. Chen, Q. Chen, Y. Wang, X. Lu, P. He, Y. Sun, V. Shah, V. Shah, R. V. Martin, S. Philip, S. Song, Y. Zhao, Z. Xie, L. Zhang, B. Alexander

    Published 2019-05-01
    “…<p>Air quality models have not been able to reproduce the magnitude of the observed concentrations of fine particulate matter (PM<span class="inline-formula"><sub>2.5</sub></span>) during wintertime Chinese haze events. The discrepancy has been at least partly attributed to low biases in modeled sulfate production rates, due to the lack of heterogeneous sulfate production on aerosols in the models. …”

    Superimposed effects of typical local circulations driven by mountainous topography and aerosol–radiation interaction on heavy haze in the Beijing–Tianjin–Hebei central and southern plains in winter by Y. Peng, H. Wang, X. Zhang, X. Zhang, Z. Liu, W. Zhang, S. Li, C. Han, H. Che

    Published 2023-07-01
    “…<p>Although China's air quality has substantially improved in recent years due to the vigorous emissions reduction, the Beijing–Tianjin–Hebei (BTH) region, especially its central and southern plains at the eastern foot of the Taihang Mountains, has been the most polluted area in China, with persistent and severe haze in winter. Combining meteorology–chemistry coupled model simulations and multiple observations, this study explored the causes of several heavy haze events in this area in January 2017, focusing on local circulations related to mountain terrain. …”
