Special Issue Information

Dear Colleagues,

Surface ozone produced by photochemical reactions contributes to climate change and has adverse effects on the ecosystem and public health. In many parts of the world, enhanced surface ozone concentrations are projected in the future, which will cause more mortalities and morbidities. In September 2021, the World Health Organization (WHO) recommended an 8 h daily maximum of 100 µg/m3 (~50 ppbv) as the threshold for ozone pollution, which is lower than current air quality standards in most regions such as the Unites States, the European Union, and China. As such, it is crucial for scientists to improve our understanding about ozone pollution and provide scientific evidence for future regulations.

The aim of this Special Issue hosted by the open-access journal Atmosphere is to recap recent advances in our understanding of ozone pollution. The topics cover all related research fields, including but not limited to: innovation in ambient ozone and precursor monitoring, updated ozone photochemical mechanism, development of new remote sensing products, advancement in air quality modeling, novel methodology (e.g., machine learning), etc. The Special Issue is also relevant to the investigation of surface ozone under global change (e.g., COVID-19 and climate change), and encompasses research quantifying health damage from ozone pollution.

Ozone (O3) is an important secondary substance that plays a significant role in atmospheric chemistry and climate change. Although O3 is essential in the stratosphere, it is harmful to human health in the troposphere, where this study was conducted. In recent years, O3 pollution in the Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (YRD), and Pearl River Delta (PRD) regions has deteriorated, which has become an important environmental problem. The generation of O3 is closely related to meteorological factors. In this study, the weather classification method was adopted to study the effect of meteorological conditions on O3 concentration. In the BTH region, Tianjin was selected as the representative city for the research. The real-time pollutants data, meteorological re-analysis data, and meteorological data in 2019 were combined for the analysis. The subjective weather classification method was adopted to investigate the effects of different weather types on O3 concentration. The backward trajectory tracking model was used to explore the characteristics and changes of O3 pollution under two extreme weather types. The results indicate there is a good correlation between O3 concentration and ambient temperature. Under the control of low pressure on the ground and the influence of southwest airflow in the upper air for Tianjin, heavy O3 pollution occurred frequently. The addition of external transport and local generation will cause high O3 values when the weather system is weak. The O3 concentration is closely related to ambient temperature. Continuous high-temperature weather is conducive to the photochemical reaction. The multi-day O3 pollution process would occur when the weather system is robust. The first and second types of extreme weather are more likely to cause persistent O3 pollution processes. Under the premise of stable emission sources, the change in weather patterns was the main reason affecting the O3 concentration. This study aims to improve O3 pollution control and air quality prediction in the BTH region and large cities in China. Full article
