“…These haze pollution events profoundly affect human health, such as respiratory system and heart (Lelieveld et al., 2020); climate, such as temperature and precipitation (Suzuki & Takemura, 2019); and ecosystem, such as growth of plankton in remote ocean areas (Li, Xu, et al., 2017). Although the Chinese government has adopted a series of control measures (e.g., the 12th Five‐Year Plan for Air Pollution Control in Key Areas and Air Pollution Prevention and Control Action Plan), some regional haze pollution events still occur in winter owing to adverse meteorological conditions (e.g., low wind speed and high relative humidity (RH)), relatively high emissions from household heating, vehicle exhausts, and industry activities, regional or long‐range transport of air pollutants, and secondary aerosol formation (J. Liu et al., 2016; X. Pan et al., 2019; Shao et al., 2019; Yao et al., 2018; F. Zhang et al., 2020; Zhang, Liu, Xu, et al., 2020; G. J. Zheng et al., 2015; H. Zheng et al., 2019; Zhong et al., 2019).…”
